3. Tissue homogenate:
With pre-cooled PBS (0.01M, pH=7.4) The tissue is flushed to remove residual blood (lysed red blood cells in the homogenate can affect the measurement), and the tissue is weighed and cut into pieces. Combining the shredded tissue with the corresponding volume PBS (Generally according to 1:9 Weight to volume ratio, such as 1g The tissue samples correspond to 9mL Of PBS The specific volume can be appropriately adjusted according to the experimental needs and recorded. Recommended in PBS Add protease inhibitor) into a glass homogenizer and ground thoroughly on ice. For further lysis of tissue cells, the homogenate can be sonicated, or freeze-thawed repeatedly. Finally, the homogenate was mixed in 5000×g Centrifugation 5~10 Minutes,
Take the supernatant for detection.

4. Cell culture supernatant or other biological specimen:
Please 1000×g Centrifugation 20 Minutes, take the supernatant to detect, or place the supernatant in -20℃ Or -80℃ Store, but repeated freezing and thawing should be avoided.

Note: Hemolysis of the specimen will affect the final test result, so hemolyzed specimens should not be tested.

Two, Reagent Preparation

The kit should be removed from the refrigerated environment and equilibrated at room temperature before use.

20× Dilution of wash buffer: distilled water according to 1 : 20 Dilution, i.e. 1 Share 20× Wash buffer plus 19 Distilled water.

 

Three, Operation steps

1. Equilibration from room temperature 20min
Take out the required slats from the aluminum foil bag after that, and seal the remaining slats with ziplock bag and put them back 4℃ 。

2. Set up standard wells and sample wells, add different concentrations of standards to each standard well 50μL ;

3. The sample to be tested is added to the sample well 50μL ;
Blank holes are not added.

4. In addition to the blank wells, horseradish peroxidase ( HRP ) Labeled detection antibody
100μL Sealing the reaction hole with a sealing plate membrane, 37℃ Incubation in water bath or incubator 60min 。

5. Discard the liquid, pat dry on absorbent paper, and fill each well with wash liquid ( 350μL ), let stand 1min , throw off the washing liquid, pat dry on absorbent paper, and repeat washing the plate 5 Times (the plate can also be washed with a plate washing machine).

6. Substrate added per well A 、 B  Each 50μL , 37℃ Incubate in the dark 15min 。

7. Add stop solution to each well 50μL , 15min  Inside, in 450nm Wavelength measurement of each well OD  Value.

 

Calculation of experimental results

Based on the tested standard OD The value is the abscissa, and the concentration value of the standard product is the ordinate. Draw the standard curve on coordinate paper or with relevant software, and obtain the linear regression equation. The sample OD Values are substituted into Eq., and the concentration of the sample is calculated.


Standard curve

Species Reactivity Rat
Theory The kit uses a double-antibody one-step sandwich enzyme-linked immunosorbent assay (ELISA). To the coated microwells pre-coated with rat parathyroid hormone (PTH) capture antibody, specimens, standards, and HRP-labeled detection antibodies were sequentially added, incubated and thoroughly washed. The color is developed with the substrate TMB, which is converted to blue under the catalysis of peroxidase and to the final yellow under the action of acid. There was a positive correlation between the depth of color and rat parathyroid hormone (PTH) in the sample. The absorbance (OD value) was measured with a microplate reader at a wavelength of 450nm, and the sample concentration was calculated.

remark

1. The standard concentrations are as follows: 2000 、 1000 、 500 、 250 、 125 、 62.5 pg/mL

2. After inspection of a large number of normal specimens, the normal concentration values of the specimens are all within the detection range provided by the kit, which are directly taken during the experiment 50μL Just load the sample. When some sample values exceed the maximum standard concentration, the sample can be appropriately diluted with sample diluent before conducting the experiment.
General Notes

1. Incubate in strict accordance with the specified time and temperature to ensure accurate results. All reagents must reach room temperature 20-25 °C prior to use. Store reagents in refrigeration immediately after use.

2. Incorrect plate washing can lead to inaccurate results. Make sure to drain the liquid from the wells as much as possible before adding the substrate. Do not allow the wells to dry out during incubation.

3. Eliminate the residual liquid and fingerprints at the bottom of the plate, otherwise it will affect the OD value.

4. The substrate color development solution should be colorless or very light in color, and the substrate solution that has turned blue cannot be used.

5. Avoid cross-contamination of reagents and specimens to avoid wrong results.

6. Avoid direct exposure to strong light during storage and incubation.

7. After equilibrating to room temperature, open the sealed bag to prevent water droplets from condensing on the cold slats.

8. Any reaction reagent cannot come into contact with the bleaching solvent or the strong gas emitted by the bleaching solvent. Any bleaching component will destroy the biological activity of the reaction reagents in the kit.

9. Expired products cannot be used.

10. If it is possible to spread diseases, all samples should be managed, and the samples and testing devices should be handled according to the prescribed procedures.

Storage Temp. Unopened kit, stored at 4 °C, shelf life 6 months.
Test Range 62.5 pg/mL-2000 pg/mL; Sensitivity: The lowest detection concentration is less than 10 pg/mL.

Works well, good price.
Color: Arctic White
Effective, fast charging. A little big and heavy but still lighter than a standard Mac charger. Works on my Macbook and my android. Got my Macbook from 0% to 50% in about 30 minutes, while I was using it.

An excellent companion for my Galaxy Tab S9,
Color: Grey, Color: Grey
I'm experimenting with replacing my Windows PC with a higher end tablet. so I wanted a docking station (let's call it the DS) to connect it to a mouse, keyboard, and most i importantly, my 28 inch display screen. So Far, So Good! This review is going through the docking station, the S9, and DEX, then displayed on a nice big screen! I REALLY like using a REAL keyboard! Once it was delivered, I rushed to my workstation to see how it worked. And it didn't! Nothing, NOTHING would work. It kept telling me to check the cables. So out of frustration, I had lunch. It turned out that the case I bought for the S9 fooled me into thinking I had the DS plugged into the tablet, but it was not. Once I had figured THAT out, the docking station, and the tablet worked well together. I like that I'm using two different RF Dongles for the keyboard and mouse plugged into the DS. I don't have to use battery power to use Bluetooth for those accessories. Plus, I still have one USB 3.0 port free. The Keyboard and Mouse don't appear to lag, at all. If it does, it is so minor that I am unable to percieve it. I like that I can power the Tablet from the DS. I'm using a 20 watt Amazon charger, and it seems to work just fine. The tablet doesn't give me any messages that I'm on a slow charge and it seems to charge as it does without the DS. The only real negative is that the cable from the DS to the Tab S9 is a bit too short for the tablet to be propped upright. The tablet display remains on, and the S Pen can be used with it. I'm thinking that I might want to use the tablet itself as a sort of touchpad sometimes. I might find applications where I would want the tablet display to remain upright. I don't know, but it MIGHT be a problem, maybe. Build quality seems good. I think the DS case is metal, at least it looks and feels like aluminum. And the cord going to the Tablet seems quite robust. I can't comment yet on reliabiy, It will take some time for that info to appear. But functionally, it is everything the seller claims it is. I am satisfied. Edit: I bought one for my wife.

Awesome tool to have
Color: Grey
The UtechSmart USB C Ethernet Multiport Adapter is a great small and versatile tool. I use it to connect my Android phone or tablet to an HDMI display that is not a smart device. I primarily use it in my kids' room to watch Netflix or YouTube videos on the larger screen, or in our travel van where I have a display for the kids to watch TV while on long travels. I love this tool because it eliminates the need for DVDs, which can get scratched and the kids get tired of watching the same movies. With this tool, I can connect their device to the display, and they can watch everything together on the display and listen through my van speakers. The tool also has other great benefits that I use with my Mac, such as the ability to connect USB devices for external storage, connect to an HDMI display, or connect to Ethernet cables. This is a great tool to have in your computer bag, especially if you use a Mac or any other computer with a USB C port. Pros: Small and lightweight Versatile Easy to use Affordable Works with a variety of devices Cons: The HDMI port only supports 4K output at 30fps The Ethernet port does not support Gigabit speeds Overall: I highly recommend the UtechSmart USB C Ethernet Multiport Adapter. It is a great tool for anyone who needs to connect their devices to a variety of displays or peripherals. Overall, I am very happy with the UtechSmart USB C Ethernet Multiport Adapter. It is a great product that I would recommend to anyone.
