Human Tissue Type Plasminogen Activator ELISA Kit (TPA)

Product details

Human Tissue Type Plasminogen Activator ELISA Kit (TPA) ab108914 is a sandwich ELISA to measure Human Tissue Type Plasminogen Activator (TPA) in serum, plasma, cell culture supernatant, cerebral spinal fluid (CSF), saliva, urine, milk with a sensitivity of 4 pg/ml.

How the assay works

A TPA specific antibody has been precoated onto 96-well plates and blocked. Standards or test samples are added to the wells and subsequently a TPA specific biotinylated detection antibody is added and then followed by washing with wash buffer. Streptavidin-Peroxidase Conjugate is added and unbound conjugates are washed away with wash buffer. TMB is then used to visualize Streptavidin-Peroxidase enzymatic reaction. TMB is catalyzed by Streptavidin-Peroxidase to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow coloration is directly proportional to the amount of TPA captured in plate.
The entire kit may be stored at -20°C for long term storage before reconstitution - Avoid repeated freeze-thaw cycles.

Assay Specificity

Our ELISA kits are rigorously validated to ensure the highest level of consistency and reproducibility. Please check the protocol booklet for more details
