The Human IgA1 (Immunoglobulin A1) ELISA Kit measures IgA1 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 IgA1 antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antibody. Then, it binds with IgA1 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 IgA1 in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

Good for the price but will not repurchase
Size: 9, Color: Grey
My husband loved these at first. Pros -easy to get on/off -stylish -comfortable -interior/exterior sole construction lasted longer than other more expensive shoes -price is great Cons -after less than a year the mouth of the shoe widened to a point where they slide off way too easy rendering them almost unwearable. -laces cannot be tightened

Cute shoe and goes with casual or formal wear. Easy to walk in if you wear heels. I’ll put additional padding at ball of shoe for comfort with standing for a long time.
