Transforming Growth Factor Beta 1 (TGFb1) BioAssay(TM) ELISA Kit (Bovine)

Sample Type:, Serum, platelet-poor plasma, tissue homogenates, cell culture supernates and other biological fluids, Intended Use: The kit is a competitive inhibition enzyme immunoassay technique for the in vitro quantitative measurement of TGFb1 in bovine serum, platelet-poor plasma, tissue homogenates, cell culture supernates and other biological fluids. Sensitivity: 4.67pg/ml, Range: 12.35-1000pg/ml, Specificity: This assay has high sensitivity and excellent specificity for detection of Transforming Growth Factor Beta 1 (TGFb1). No significant cross-reactivity or interference between Transforming Growth Factor Beta 1 (TGFb1) and analogues was observed. Precision: Intra-Assay: CV<10% , Inter-Assay: CV<12%, Test Principle: This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to TGFb1 has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled TGFb1 and unlabeled TGFb1 (Standards or samples) with the pre-coated antibody specific to TGFb1. After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of TGFb1 in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of TGFb1 in the sample.
