The Human CD20 (B-lymphocyte antigen CD20) QuickTest ELISA Kit measures MS4A1 in Human Serum, Plasma, Cell Culture Supernatant, Cell Lysate or Tissue Lysate. This kit was based on sandwich ELISA method. The experiment lasted 120 minutes. Capture antibody was conjugated to an affinity tag that was recognized by a specific antibody coated on the QuickTest plate. Add the Cap/Det Ab working solution into each well, then add the standards and pilot samples into individual wells. If the sample contains MS4A1, a capture antibody-MS4A1-biotin-detection antibody complex was formed. After incubation, unbound conjugates were removed by wash buffer. HRP-Streptavidin was added. After washing, TMB substrates were added to visualize HRP enzymatic reaction. 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. The concentration of MS4A1 in the sample was calculated by drawing a standard curve. The concentration of the target substance is proportional to the OD450 value.

What a disappointment!
Format: Board book
What you see is what you get. You pay all that money just to get a handful of unexciting sounds. What a disappointment!

Christmas present

This book was for a young girl for Christmas and she just loved it from what her mom said to me. She really loved being able to touch the different animals in the book.
