产品简介

Catalog No.

PY2270

Source

Human Cytokines

UniProt ID

P01137

Reactivity

Measure by its ability to inhibit the IL-4 dependent proliferation in HT-2 cells. The ED50 for this effect is <0.1 ng/mL. The specific activity of recombinant human TGF beta 1 is approximately >5 x 107 IU/mg. Measure by its ability to induce proliferation in MCF-7 cells. The ED50 for this effect is <3.2 ng/mL.

Application

Cell culture, Elisa

Calculated Mol Weight

14 kDa

Observed Mol Weight

13 kDa

Recommended Dilution

It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved. In some experiments, it recommends to add 10 mM HCl when reconstitute lyophilized protein.

Alternative Names

Differentiation inhibiting factor, Cartilage-inducing factor, CED, DPD1, IBDIMDE, LAP, TGFB

Host

Escherichia coli

Isotype

Clonality

Modification

Buffer System

<0.1 EU per 1 μg of the protein by the LAL method. The protein was lyophilized from a 0.2 µm filtered solution containing 1X PBS, pH 8.0.

Storage Condition

Lyophilized protein should be stored at -20°C for 1 year. Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months.

Description

Transforming growth factor beta 1 or TGF-β1 is a polypeptide member of the transforming growth factor beta superfamily of cytokines. It is a secreted protein that performs many cellular functions, including the control of cell growth, cell proliferation, cell differentiation, and apoptosis. In humans, TGF-β1 is encoded by the TGFB1 gene.
