The Human CD21 (Complement Receptor 2) ELISA Kit measures CD21 in Human 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 CD21 antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antibody. Then, it binds with CD21 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 CD21 in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

Gorgeous Clutch Bag
Size: One Size, Color: B4/Black
This Coach Clutch bag it’s very elegant. I didn’t realize that this clutch bag was patented leather and it goes perfect with my shoes. The clutch bag is very small and you can’t fit your cell phone inside of it. Other than that minor issue it’s perfect. I recommend this clutch bag.

Timeless Luxury and Everyday Elegance

I am absolutely in love with my Coach bag! The quality is exceptional—the leather is soft yet durable, and the stitching is flawless. It feels luxurious without being over the top, and the design is timeless, making it perfect for everyday use or special occasions. The compartments are thoughtfully designed, so it’s easy to stay organized while on the go. Definitely worth every penny—I get compliments on it everywhere I take it!
