Porcine CD4 (Cluster of Differentiation 4) ELISA KitThe Porcine CD4 (Cluster of Differentiation 4) ELISA immunoassay kit uses the Sandwich ELISA principle. The micro ELISA plate provided in this kit has been pre coated with an antibody specific to Porcine CD4. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody.

The Porcine CD4 (Cluster of Differentiation 4) ELISA immunoassay kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Porcine CD4. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Porcine CD4 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Porcine CD4, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Porcine CD4. You can calculate the concentration of Porcine CD4 in the samples by comparing the OD of the samples to the standard curve.

Best frother ever!
Color: Flat Black
Super easy to use! Love the 3 speed mode. Makes my morning coffee a breeze to make. Also love the fact that it’s rechargeable. So far only charged once and it’s long lasting. Favor part about it is the storage, doesn’t need to stand straight and be out. Can be easily cleaned and stored away with the cover. Feels very high quality. Highly recommend!

Works Great So Far
Color: Flat Black
I've only used this item for one week. But it is working great. I primarily bought it to use when mixing protein powder, and it has performed great. The only concern that I might share is that it is made fairly lightweight, and I wonder how long it will last. But can, up to this point, recommend it.

Strong, Durable, and SIMPLE Frother
Color: Gray
Excellent frother! It is ‘SIMPLE’, yet very efficient blending. I love that it included a set of long-lasting batteries. The motor on this frother is strong and works great. The item itself is of durable quality. I have had mine for about 9 months and use it daily for my coffee and other drinks throughout my week, and the battery is still running. I even give it a spin after washing the frother spinner/coil. This helps to dry it thoroughly, as the motor is strong enough to blow away any excess water - and still - the batteries are functioning well. The price is just right…very affordable compared to other brands. I’m very pleased with this purchase and absolutely love that it also came with a stand. I display it on my counter everyday. There are 3 solid and Simple colors to choose from, making this an easier shopping experience. Excellent choice for gifting!

Found the perfect chai frother on a budget!
Color: Glossy Black
Okay so I'll be honest, I spent way too long researching milk frothers before pulling the trigger on this one lol. As someone who grew up drinking chai every single day, having a good frother is kind of a big deal in my house. This little thing has been absolutely worth every penny. First off – it's SO easy to use. My 7 year old actually thinks it's the coolest thing ever and wants to help make my morning coffee now, which is honestly adorable. It just works, no fuss, no learning curve. What really sold me compared to other options was the USB-C charging. No more buying AA batteries every few weeks – that stuff adds up! I just plug it into the same charger as my phone. Super convenient. And here's a small thing that matters more than you'd think – it stands on its own! I don't need a separate stand cluttering up my already busy kitchen counter. Build quality feels solid, the stainless steel whisk looks clean and is easy to rinse off. For the price, honestly I expected less. Highly recommend if you're on the fence!
