Product Info

• Predicted Species Reactivity: Human
• Application: ELISA
• ELISA Kit Detection Method: Colorimetric, OD450 nm
• ELISA Kit Duration: ~ 3 Hours
• ELISA Kit Principle: Aviva's human TGF beta 1 ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A polyclonal antibody from chicken specific for TGF beta 1 has been precoated onto 96-well plates. Standards(CHO, A279-S390) and test samples are added to the wells, a biotinylated detection polyclonal antibody from chicken specific for 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 absorbance of yellow is proportional to the human TGF beta 1 amount of sample captured in plate.

  Principle: Aviva’s human TGFβ1 ELISA Kit was based on standard sandwich
  enzyme-linked immune-sorbent assay technology. Human TGFβ1
  specific-specific polyclonal antibodies were precoated onto 96-well plates. The
  human specific detection polyclonal antibodies were biotinylated. The test
  samples and biotinylated detection antibodies were added to the wells
  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 human TGFβ1 amount of sample
  captured in plate.
  Notes: 1. To inspect the validity of experiment operation and the appropriateness of sample dilution proportion, pilot
  experiment using standards and a small number of samples is recommended.
  2. The TMB Color Developing agent is colorless and transparent before using, contact us freely if it is not the case.
  3. Before using the Kit, spin tubes and bring down all components to the bottom of tubes.
  4. Duplicate well assay is recommended for both standard and sample testing.
  5. Don’t let 96-well plate dry, for dry plate will inactivate active components on plate.
  6. Don’t reuse tips and tubes to avoid cross contamination.
  7. To avoid to use the reagents from different batches together.
  8. In order to avoid marginal effect of plate incubation due to temperature difference ( reaction may be stronger in the
  marginal wells), it is suggested that the diluted ABC and TMB solution will be pre-warmed in 37C for 30 min before
  using.
  Background: 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 TGFβ1 with the molecular mass of 25KDa
  Activating Reagent: TGFβ1 is mostly contained as inactive form in samples, please activate it before assay. Don’t activate recombinant TGFβ1.
