The Rat CPB1 (Carboxypeptidase B) ELISA Kit measures Cpb1 in Rat 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 Cpb1 antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antibody. Then, it binds with Cpb1 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 Cpb1 in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

Comfort and Appearance
Size: 9, Color: Black
The shoes were as advertised. Marc Joseph (I hav 4 other pairs) are the perfect shoes for me with my physical needs. Additionally they are exceptionally comfortable and attractive. This pair I returned because they weren’t quite the right fit for me. They are, like my other Marc Joseph shoes, very well made and very attractive.

Ok in a pinch. Can get better shoes for the price. Wide aren’t wide
Size: 9 Wide, Color: Black/Black
These were ok comfortable. Would have preferred at the price point to be a little more comfortable. For being a wide size, the shoe was rather tight on my feet. Quality is ok. It passed for the wedding. Would probably have taken more time to pick something different if I had the ability to. This was a last minute purchase.
