TGF-beta1 (Transforming Growth Factor beta1) BioAssay(TM) ELISA Kit (Rabbit)

Transforming growth factor-beta1(TGF-beta1) is a multifunctional peptide that controls proliferation, differentiation, and other functions in many cell types. Many cells synthesize TGF-beta and essentially all of them have specific receptors for this peptide. TGF-beta regulates the actions of many other peptide growth factors and determines a positive or negative direction of their effects. TGFbeta1 is known for its potent and diverse biological effects, including immune regulation, and cell growth and differentiation. TGFbeta1 is also an important mediator of bone remodeling. TGFbeta1, a potent keratinocyte growth inhibitor, has been shown to be overexpressed in keratinocytes in certain inflammatory skin diseases and has been thought to counteract the effects of other growth factors at the site of inflammation. TGF-beta1, a multifunctional cytokine with fibrogenic properties, has been implicated in the pathogenesis of the vascular and target organ complications of hypertension. TGF-beta1 may also regulate blood pressure via stimulation of endothelin-1 and/or renin secretion. TGFbeta1 is secreted as a latent form, which consists of its mature form and a latency-associated peptide(beta1-LAP) in either the presence or the absence of additional latent TGF-beta1-binding protein. The standard product used in this kit is recombinant TGFbeta1 with the molecular mass of 25kD. Sample Type: Serum, urine, cell culture supernates, plasma (EDTA). Intended Use: Sandwich High Sensitivity BioAssay(TM) ELISA kit for Quantitative Detection of Rabbit TGF beta 1. Sensitivity: <1pg/ml, Range: 15.6pg/ml-1000pg/ml, Specificity: Recognizes natural and recombinant Rabbit TGF beta 1. There is cross-reactivity with TGF beta 2, TGF beta 3, TGF beta 5 (<1%). Test Principle: This Rabbit TGF Beta 1 BioAssay(TM) ELISA Kit was based on standard sandwich enzyme-linked immune- sorbent assay technology. A monoclonal antibody from mouse specific for Rabbit TGF Beta 1 has been precoated onto 96-well plates. Standards(Expression system for standard: CHO, Immunogen sequence: A279-S390) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for Rabbit TGF Beta 1 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the Rabbit TGF Beta 1 amount of sample captured in plate.
