GMP TGF beta 1/TGFB1 Protein, Human (CHO)

Cat. No.: HY-P70543G
COA Handling Instructions

TGF beta 1/TGFB1 Protein is initially identified as a growth factor that induces the growth of rodent fibroblasts. TGF beta 1/TGFB1 Protein inhibits the cell cycle in the G1 phase. TGF beta 1/TGFB1 is an endogenous factor controlling apoptosis in normal and pathological tissues. GMP TGF beta 1/TGFB1 Protein, Human (HEK293) is a GMP-grade recombinant protein (A279-S390) produced by CHO cells.

GMP-grade recombinant proteins are produced under independent QA supervision, as well as quality records and full traceability.

Description

TGF beta 1/TGFB1 Protein is initially identified as a growth factor that induces the growth of rodent fibroblasts. TGF beta 1/TGFB1 Protein inhibits the cell cycle in the G1 phase. TGF beta 1/TGFB1 is an endogenous factor controlling apoptosis in normal and pathological tissues. GMP TGF beta 1/TGFB1 Protein, Human (HEK293) is a GMP-grade recombinant protein (A279-S390) produced by CHO cells[1][2].

Background

TGF beta 1/TGFB1 Protein (transforming growth factor beta 1) is a multifunctional cytokine, which is synthesized by almost all cells. TGF beta 1/TGFB1 Protein has a high ability to bind with TGFbRII[3].
The sequence of amino acids in TGFb1 proteins from different species is very stable, which leads to the conclusion that in the process of evolution, TGFb has been only slightly altered, and that both in humans and in animals, its function is similar. TGF beta 1/TGFB1 Protein is secreted as an inactive peptide, forming part of a ‘latent complex’ consisting of a mature TGFB1 dimer non-covalently bound to its latency-associated peptide (LAP) and, via LAP, to latent TGFB-binding proteins (LTBPs). Activated TGF beta 1/TGFB1 Protein binds to ubiquitously expressed cell-surface TGFB1 type I receptors (TGFBRI) and type II receptors (TGFBRII), which are transmembrane serine/threonine kinases[4].
TGF beta 1/TGFB1 Protein regulates cell proliferation, growth, differentiation and cells movement. TGFb1 has immunomodulatory effects. TGF beta 1/TGFB1 Protein has profibrogenic effects. TGF beta 1/TGFB1 Protein action can be local and systemic. TGF beta 1/TGFB1 Protein plays a driving role in development, fibrosis and cancer[4].

In Vitro

TGFB1 human (0.2 ng/mL) upregulates LINC00941[5].
TGF-β1 (0.2 ng/mL) significantly and maximally inhibits the growth of MLE cells[6].
TGF–β1 (5 ng/ml) results in a significant increase in the protein and mRNA levels of IL-6 in HTM cells[7].

Biological Activity

The specific activity is > 2×10 7 U/mg.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Reconstitution Calculator

  • Dilution Calculator

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
