The Input samples were stored at -80°C for later use. (2) animal tissues ① lysis preparation: 990uL IP lysis buffer was added to 10uL Protease inhibitor(100×) and then mixed. ② Fresh or low-temperature tissues (about 0.3g) were placed in a pre-cooled mortar after sterilization, and rapidly ground to powder by adding liquid nitrogen. About 1/4 of the tissue samples were collected for RNA extraction in the subsequent Input group (stored in EP tube without nuclease and stored at -80°C). ③ Add 800uL lysate to the remaining sample of mortar, grind it on ice for 5-10min until the sample is fine and homogenized, and transfer it to a new EP tube. Then add the remaining 200uL lysate to the mortar to collect the remaining sample, and transfer it to the EP tube as well. (4) samples containing homogenate of 30 min EP tube fully crack on the ice, once every 5 min vortex, 10 s/time; (5) pyrolysis with ultrasonic cell disruption instrument ice bath after the completion of ultrasonic 8 to 10 min, 20% power, ultrasonic 3 s, intermittent 3 s; ⑥ Centrifuged at 12000rpm for 10min at 4℃, the supernatant was taken, and then IP Lysis Buffer was added to the supernatant to a volume of 1mL, mixed, and divided into three parts according to 450uL (control group), 450uL (experimental group), and 100uL (Input). The Input samples were stored at -80°C for later use.

Note: If prey RNA is known, it is necessary to determine the obtained RNA in advance. Three ways to be reserved for prey RNA 1/4 as Input for subsequent test for reference. 2, magnetic beads bind to RNA Preparation: (1) Magnetic Beads take 2 1.5 mL without nuclease EP mark tube in the control group and experimental group, remove the kit in Nucleic Acid - Compatible Streptavidin Magnetic Beads, after thoroughly incorporated, taking 40 join the EP tube ul Magnetic Beads; 2. 2 EP tube in the magnetic rack, let stand for 1 min, abandon protection and liquid; ③ The magnetic beads were washed with 200uL Wash Buffer I, and the beads were resuspended by vortexing the EP tube. After low-speed centrifugation, the beads were placed on the magnetic frame, left for 1min, and Wash Buffer I was absorbed and discarded. (4) to join in washing complete magnetic beads 300 ul 1 x RNA binding buffer, the vortex shock EP heavy suspension magnetic beads; (5) to add 150 into the experimental group EP tube pmol biotin labeled probe experiment, EP tube to the control group to join 150 pmol biotin labeling on the control of the probe, and pipetting gun gently blowing mixture; ⑥ Place on a silent mixer and incubate for 2 hours at room temperature with rotation. 3, RNA-magnetic bead complexes bind to proteins A: RNA-bead complex bound to protein (optional) ① Two EP tubes that had completed RNA-magnetic bead incubation were placed on a magnetic frame, and the supernatant was discarded. (2) with 200 ul for Wash Buffer I washing magnetic beads, vortex tube shock EP heavy suspension magnetic beads, microcentrifuge after low-speed centrifugal on magnetic rack, let stand for 1 min, abandon absorption for Wash Buffer, the steps to implement three times; (3) according to the following table in order to wash finish adding volume of corresponding reagent EP tube;
④ After vortexing and mixing, the mixture was stirred and incubated at 4°C overnight. B: RNA-magnetic bead complex binding to RNA (optional) ① Two EP tubes that had completed RNA-magnetic bead incubation were placed on a magnetic frame, and the supernatant was discarded. ② The magnetic beads were washed with 200uL Wash Buffer I, and the beads were resuspended by vortexing the EP tube.

| Description |
I. Experimental principle RNA pull-down is a technique for studying the binding of RNA to protein/RNA in cells. RNA is first labeled (such as biotin labeling), and then incubated with cell lysates to form RNA-RNA/protein complexes, and then the bound RNA or protein can be detected. After elution of the complex, real-time quantitative PCR (RNA pull down QPCR) or high-throughput sequencing (RNA pull down seq) were used to identify whether the target RNN interacted with certain RNA molecules. Western blot (pull down-WB) assay and mass spectrometry (pull down -MS) technology was used to detect whether the target RNA interacted with certain proteins. |

These are cheaply made, and garbage, highly dangerous letting a dog chew on a battery pack
Color: Grid Pattern
These units are garbage. I got one for each of my dogs charged it up turned it on put it inside the rubberized ball shell and securely fastened it less than two minutes later my dog had taken it apart by just biting it and then started to chew on the battery and motor unit. So if you wanna have a lithium polymer fire in your house and potentially kill your animal, go ahead and get this, but if you do not want a fire in your house and you want your animal to live then absolutely do not buy this garbage it’s cheap we made and it’s not strong enough for any dog

Good Product, but images over promise just a little.
Color: Ripple Pattern
- Performs well on tile and low pile carpet. On artificial grass it doesn’t roll even on the highest setting; it only vibrates. Watch the video.
- Still fun for my pup. I’ve only had it a day so no clue about durability although my dog is a strong chewer.
- Price Value: When purchased it was 2 balls for the same price of a single ball from competitor.
- Material feels like a Nerf football. Easy to disassemble and charge.

Best jiggle balls we have found thus far
Color: Ripple Pattern
Yes ! First off this was a great value for the money. The balls function just as described and they have a decent battery life. They entertain both our goldens for a good bit of time. They have so far held up and not been chewed up . We limit the time and put them away after that time.. to avoid them being destroyed. Of all the jiggle balls we have purchased these are by far the best. The way the component is encased in the rubber protects it.. and it screws together very well. I am so pleased with these !

Highly recommend for pet owners looking to keep their dogs busy and happy!
Color: Grid Pattern
These interactive dog toys were a great surprise! My dog was instantly interested in the bouncing and vibrating movement, and it kept him entertained much longer than regular toys. I like that the balls are rechargeable and washable, which makes them easy to maintain after outdoor play. The automatic motion is fun and unpredictable enough to keep pets curious and active. Great value for a 2-pack, especially for energetic dogs that need extra stimulation during the day. Highly recommend for pet owners looking to keep their dogs busy and happy!
