Human TGF-Beta 1 / TGFB1 Protein, premium grade

分子别名(Synonym)

CEDLAP,TGF-beta 1,TGFB1,DPD1,TGF-beta-1,TGFB

表达区间及表达系统(Source)

Human TGFB1, premium grade (TG1-H4212) is expressed from human 293 cells (HEK293). It contains AA Ala 279 - Ser 390 (Accession # P01137-1).

Predicted N-terminus: Ala 279

It is produced under our rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. Product performance is carefully validated and tested for compatibility for cell culture use or any other applications in the early preclinical stage. When ready to transition into later clinical phases, we also offer a custom GMP protein service that tailors to your needs. We will work with you to customize and develop a GMP-grade product in accordance with your requests that also meets the requirements for raw and ancillary materials use in cell manufacturing of cell-based therapies.

TGF-beta 1 Structure

This protein carries no "tag".

The protein has a calculated MW of 12.8 kDa (monomer). The protein migrates as 14 kDa (monomer) under reducing (R) condition, and 25 kDa (Dimer) when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE).

内毒素(Endotoxin)

Less than 0.1 EU per μg by the LAL method.

宿主蛋白残留(Host Cell Protein)

<0.5 ng/µg of protein tested by ELISA.

宿主核酸残留(Host Cell DNA)

<0.02 ng/μg of protein tested by qPCR.

无菌(Sterility)

The sterility testing was performed by membrane filtration method.

支原体(Mycoplasma)

Negative.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in 0.085% TFA in 30% ACN with trehalose as protectant.

电泳(SDS-PAGE)

TGF-beta 1 SDS-PAGE

Human TGFB1, premium grade on SDS-PAGE under reducing (R) and non-reducing (NR) conditions. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95% (With Star Ribbon Pre-stained Protein Marker).

 

活性(Bioactivity)-Bioactivity CELL BASE

TGF-beta 1 CELL

Human TGFB1, premium grade (Cat. No. TG1-H4212) inhibits the Human IL-4, premium grade (Cat. No. IL4-H4218) dependent proliferation the TF-1 cells. The specific activity of Human TGFβ1, premium grade is > 8.00ⅹ10^6 IU/mg, which is calibrated against transforming growth factor β1 (NIBSC code: 89/514) (QC tested).

Protocol

 

活性(Bioactivity)-ELISA

TGF-beta 1 ELISA

Immobilized Human TGFB1, premium grade (Cat. No. TG1-H4212) at 0.2 μg/mL (100 μL/well) can bind Human TGFBR2, Fc Tag (Cat. No. TG2-H5252) with a linear range of 0.2-2.5 ng/mL (QC tested).

Protocol

 

背景(Background)

Transforming growth factor beta 1 ( TGFB1) is also known as TGF-β1, CED, DPD1, TGFB. 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. The TGFB1 protein helps control the growth and division (proliferation) of cells, the process by which cells mature to carry out specific functions (differentiation), cell movement (motility), and the self-destruction of cells (apoptosis). The TGFB1 protein is found throughout the body and plays a role in development before birth, the formation of blood vessels, the regulation of muscle tissue and body fat development, wound healing, and immune system function. TGFB1 is particularly abundant in tissues that make up the skeleton, where it helps regulate bone growth, and in the intricate lattice that forms in the spaces between cells (the extracellular matrix). Within cells, this protein is turned off (inactive) until it receives a chemical signal to become active. TGFB1 plays an important role in controlling the immune system, and shows different activities on different types of cell, or cells at different developmental stages. Most immune cells (or leukocytes) secrete TGFB1. TGFB1 has been shown to interact with TGF beta receptor 1, LTBP1, YWHAE, EIF3I and Decorin.
