The Rat PRF1 (Perforin-1) ELISA Kit measures PRF1 in Rat Serum, Plasma, Cell Culture Supernatant, Cell or Tissue Lysate. This kit is based on Double antibody-Sandwich ELISA detection method and takes 4h assay time. The microplate provided in this kit has been precoated with anti PRF1 antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antibody. Then, it binds with PRF1 bound to precoated antibody. Wash unbound components and add HRP-Streptavidin Conjugate (SABC). Wash unbound components again and add TMB substrate solution. Then, TMB was catalyzed by HRP to produce a blue color product that turned yellow after adding a stop solution. Read the O.D. absorbance at 450nm in a microplate reader. Calculate the concentration of PRF1 in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

Good seal and cute in photos
Color: Pop Rainbow Sweet Purple, Color: Pop Rainbow Sweet Purple
We had the prior version of these Speedo kids’ goggles and these ones are much better. First, they have the same great no catch string that comes on and off without pulling hair. But they also have a better seal around the eyes, and so after days of hotel pool and swim class swimming we haven’t had a leak yet. The new frames also look a lot more like really cute kids’ sunglasses, so they’re great for all-day hotel pool wear and look great in our holiday photos.

4 year old approved!
Color: Pop Rainbow Flare Pink, Color: Pop Rainbow Flare Pink
These goggles are absolutely perfect for my 4.5 year old. She is obsessed with them and they are easy enough for her to put on herself. We've been using for over 6 months now and they are still in perfect condition! Highly recommend these because they seem very durable and difficult to break.

Comfortable and don't leak
Color: Blue
These are my kids favorite swim goggles. The adjusting in the back helps them fit better and doesn't get tangled in his hair. This also don'ts leak like some other brands. Mom approved.

Cooler
Color: Clear Blue 4 PK, Size: 4 Pack
I absolutely love these Cool Coolers by Fit & Fresh! They are truly amazing and have made such a difference in keeping my food fresh. The slim XL design is perfect because it fits easily into my lunch bag or cooler without taking up too much space. What really impressed me is how quickly they freeze and how long they stay cold. They keep everything nicely chilled for hours, which is exactly what I need for busy days. Plus, they are reusable and very durable, so they’re a great eco-friendly option. The quality is excellent, and the performance is even better than I expected. I highly recommend this product to anyone looking for reliable and efficient ice packs!

Keep Everything Cold All Day!
Color: Multi (4 Pack), Size: 4 Count (Pack of 1)
These ice packs are absolutely perfect! The 4-pack gives me plenty of options to keep drinks, lunch, and snacks cold no matter where I go, whether it’s work, a picnic, or a day trip. They freeze quickly, stay cold for hours (I live in a really hot climate and they stay cold in my car all day), and fit perfectly in lunchboxes, coolers, or insulated bags without taking up too much space because they are pretty thin. The packs are very durable, completely leak-proof, and easy to clean, which makes them convenient for everyday use. I love that having four means I can always have a frozen one ready while the others are thawing. Overall, this set is reliable, long-lasting, and makes keeping food and drinks cold simple and stress-free — I would highly recommend them to anyone!
