The Human SIGA (Secretory Immunoglobulin A) QuickTest ELISA Kit measures sIgA in Human Serum, Plasma, Cell Culture Supernatant, Cell Lysate or Tissue Lysate. This kit was based on sandwich ELISA method. The experiment lasted 120 minutes. Capture antibody was conjugated to an affinity tag that was recognized by a specific antibody coated on the QuickTest plate. Add the Cap/Det Ab working solution into each well, then add the standards and pilot samples into individual wells. If the sample contains sIgA, a capture antibody-sIgA-biotin-detection antibody complex was formed. After incubation, unbound conjugates were removed by wash buffer. HRP-Streptavidin was added. After washing, TMB substrates were added to visualize HRP enzymatic reaction. 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. The concentration of sIgA in the sample was calculated by drawing a standard curve. The concentration of the target substance is proportional to the OD450 value.

Fits my Accord perfectly!
Size: 8.8" x 9.3" x 1.2"
Fits my 2008 Accord perfectly and feels just as sturdy as the OEM I used before, which cost nearly twice as much. Plus, it includes activated carbon, something the OEM didn’t have.

One place wanted $85 to replace this! Another wanted $50! I ordered this for $10, watched a YouTube video and did it myself! Super easy!
