The Human CYFRA21-1 (CytokeRatin Fragment Antigen 21-1) ELISA Kit measures CYFRA21-1 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 CYFRA21-1 antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antibody. Then, it binds with CYFRA21-1 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 CYFRA21-1 in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

Failed at 3 months.
Color: Silver/Battery
I ordered this on Oct 6th. When I first got it, it worked great. I didn't need to use it all that often but here it is, 3 months later, and it is broken. It fails to cut open any cans. Tried on multiple cans over multiple times but it just spins cutting nothing. Total waste of money. Avoid this product if you care about durability or longevity of your purchases.

Works well but doesn't stop on it's own
Color: Green/Battery
The price was decent and I like the color. It is easy to get started and it came with batteries which was unexpected and nice! Like others have said, it doesn't stop on it's own like it's supposed to, which is my only drawback with it. I had thought that if I pushed the button on the top it might stop it, but all that does is reverse the direction of the opener. 4 stars because it does work, but having to fool around with it to make it stop makes it lose a star for me.

Not bad at all
Color: Green/Battery
Super EASY for my 83 old mother with arthritis to use. It’s not “speedy” but it works great.
