The Human CA19-9 (CarbohydRate antigen19-9) QuickTest ELISA Kit measures CA19-9 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 CA19-9, a capture antibody-CA19-9-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 CA19-9 in the sample was calculated by drawing a standard curve. The concentration of the target substance is proportional to the OD450 value.

Classy bag!
Size: One Size, Color: Black
This is a beautiful, high quality Kate Spade purse. Got it for my college daughter for a Christmas gift and she loves it! It’s the perfect size to carry a 16!oz water bottle and/or a small umbrella along with a wallet and phone. She literally said “this purse is going to be life changing!” She’s been carrying just a small wristlet for years and I guess she never has what she needs. This is a perfect, classy piece for her as she transitions to the next phase of life.

Cute purse. Good quality. Kind of small for every day (unless you're a small purse person) but great for a night out or a lunch outing.
