Recombinant Human GARP&Latent

Recombinant Human GARP&Latent TGF Beta-1 

Complex Protein (N-6His, C-3*Strep) (C14X)

产品说明(Description)

Recombinant Human GARP&Latent TGF Beta-1 Complex Protein  is produced by our Mammalian expression system and the target gene encoding Leu30-Ser390&His20-Asn627 is expressed with a 6His tag at the N-terminus and a 3Strep at the C-terminus.

Accession #: P01137&Q14392

Known as: NA

 

制剂(Formulation)

Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4.

 

质量控制(Quality Control)

Purity:        Greater than 95% as determined by reducing SDS-PAGE.    

Endotoxin: Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.

 

 

复溶(Reconstitution)

Always centrifuge tubes before opening.  Do not mix by vortex or pipetting. 

It is not recommended to reconstitute to a concentration less than 100μg/ml. 

Dissolve the lyophilized protein in distilled water.

Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

 

保存(Storage)

Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. 

Reconstituted protein solution can be stored at 4-7°C for 2-7 days.  

Aliquots of reconstituted samples are stable at < -20°C for 3 months.

 

背景(Background)

Transforming Growth Factor β-1 (TGFβ-1) is a secreted protein which belongs to the TGF-β family. TGFβ-1 is abundantly expressed in bone, articular cartilage and chondrocytes and is increased in osteoarthritis (OA). TGFβ-1 performs many cellular functions, including the control of cell growth, cell proliferation, cell differentiation and apoptosis. The precursor is cleaved into a latency-associated peptide (LAP) and a mature TGF β -1 peptide. Leucine Rich Repeat Containing 32 (LRRC32), also known as Glycoprotein A Repetitions Predominant (GARP), has been postulated as a novel surface marker of activated T(regs). LRRC32 binds directly to the TGF-beta latency associated peptide (LAP) and tethers latent TGF-beta on the surface of activated Treg cells. The presentation of TGF-beta on Tregs contributes to their ability to suppress naïve T cell proliferation.
