The Human anti 21-OH Ab (anti 21-hydroxylase antibody) ELISA Kit measures anti 21-OH-Ab in Human Serum, Plasma, Cell Culture Supernatant, Cell or Tissue Lysate. This kit is based on Double antigen-Sandwich ELISA detection method and takes 4h assay time. The microplate provided in this kit has been precoated with antigen. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antigen. Then, it binds with anti 21-OH Ab bound to precoated antigen. 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 anti 21-OH Ab in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

Good product
Let me tell you just how much I love this can opener. I am 80 yrs old and the hand opener was becoming a real challenge to use, this is sooooooo easy, holds it's charge for a long time and the lids don't have any rough edges. Great product for an excellent price.

It worked on all size of cans
Eh pretty good for the whopping 3 weeks I had it. Came home one day and it was broken. It still operated. As in all functions were there but it wouldn't latch onto cans anymore. I think one of my adult kids dropped it. Honestly surprised motor still operated after it's drop.

Didn't work out for me after a few uses.
Broke after only like 5 uses...not worth the money. Doesn't stay sharp nor does it auto-clamp onto cans after such uses. Thought it worked only to find out it didn't cut the can and left little metal shavings from just kinda "scratching" the can and I ended up getting a splinter. Thought it was low on battery and fully charged only for it to keep not cutting the can. Trashed it just gonna buy a regular stand up from walmart or something.

Works great!
Color: Black with Silver
I am absolutely thrilled with the HouseSapp Rechargeable Electric Can Opener! This handy gadget has made opening cans a breeze. It’s so easy to use — simply press a button, and it automatically opens the can smoothly and safely. No more struggling with manual can openers or worrying about sharp edges! The rechargeable feature is fantastic. I love that it’s cordless, which makes it so much more convenient to use anywhere in the kitchen without needing to find an outlet. It holds a charge really well, and I haven’t had to recharge it too often, even after using it multiple times. The design is sleek and modern, fitting comfortably in my hand, and it doesn’t take up too much space in the kitchen drawer. The smooth edge left by the can opener is a huge plus, as it prevents any cuts when handling the lid afterward. Overall, this is a wonderful, practical addition to my kitchen, and I highly recommend it to anyone looking for a hassle-free can-opening experience!
