Kit Principle:
Aviva Systems Biology COL1A2 ELISA Kit (Human) (OKCD00157) is based on standard sandwich enzyme-linked immuno-sorbent assay technology. An antibody specific for COL1A2 has been pre-coated onto a 96-wellplate (12 x 8 Well Strips). Standards or test samples are added to the wells, incubated and removed. A biotinylated detector antibody specific for COL1A2 is added, incubated and followed by washing. Avidin-Peroxidase Conjugate is then added, incubated and unbound conjugate is washed away. An enzymatic reaction is produced through the addition of TMB substrate which is catalyzed by HRP generating a blue color product that changes to yellow after adding acidic stop solution. The density of yellow coloration is read by absorbance at 450 nm and is quantitatively proportional to the amount of sample COL1A2captured in well.

1. What sample types were used with this kit?

We used cell culture supernatants from fibroblasts treated with and without TGF-b1.

2. Were these samples validated or characterized as positive and/or negative controls?

Samples were validated as functional fibroblasts.

3. What dilution worked for your samples?

We didn’t dilute the cell culture supernatant.

4. Please provide a brief summary of your sample preparation method:

Cell culture supernatants from fibroblasts were collected with or without stimulus for Col1A2 production and centrifuged to remove any particulates and stored at <80C until used for the assay.
