The IL12A (Interleukin 12A) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human IL12A. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human IL12A. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human IL12A, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human IL12A in the samples is then determined by comparing the OD of the samples to the standard curve.

This is a favorite…
Format: Board book
I love Eric Carle and this book always brings smiles to little faces! The illustrations/paintings are so fun and vibrant and the animal sounds are very exciting for babies and toddlers to hear. When they are able to push the images themselves to make the sounds.. it’s a very proud moment for them😉. Books can help create and sustain wonder. There are so many beautiful ones..and this is a classic.

Great book
Format: Board book
Arrived a few days ahead of schedule, all electronic buttons work, no wear and tear at all really (for being a used book at 3$ instead of 22$ it was a hell of a deal) would gladly by from this thrift store again. As for the book my toddler LOVES it. Animal sounds are clear and entertaining to him, there is also some weather sounds for storms and rain. And some random buttons for up and jump and a weird musical cues (overall less then 5 semi pointless buttons) it’s a good one for toddlers :) ADDED INFO : okay so the back is so heavy it’s completely split into two . Not the sellers fault- it’s just seen that much use... repaired it with cloth and electrical tape we will see how it does.
