CST4 present in the sample is added and binds to antibodies coated on the wells. And then biotinylated Human CST4 Antibody is added and binds to CST4 in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated CST4 antibody. After incubation unbound Streptavidin-HRP is washed away during a washing step. Substrate solution is then added and color develops in proportion to the amount of Human CST4. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450 nm.

Sturdy & we repurchase yearly for Hubby’s refresh
Color: Brown (Rodeo)
This is my hubbys tried and true wallet. He requests this same one every year as a refresh. He wears his 24/7 in his back pocket so it gets discolored but still holds its shape pretty well with a slight bend.

Nice and durable
Color: Black (Trifold)
The trifold is a bit thick, but fits right where my old leather wallet sat. Lots of room for cards and cash.

8/10 Front Pocket Wallet
Color: Black (Front Pocket)
It's a pleasing solution for me. The slim, pocketed design fits well in my front pocket. It probably fits other pockets well too. It's not perfect. But, it's solving for an imperfect solution that Apple is takling with their phones. Tap to pay with phones and digital ID will change the market for wallets. The physical size of cards limits how readily you can access any one card. It takes a bit of extra dexterity to pinch or slide some of the cards out. Ideally you'd have 4 on the outside, with remaining cards tucked in the center pocket. I just need more than 1/4 inch of card face to slide one out readily.
