Biotinylated Human Integrin alpha V beta 8 (ITGAV&ITGB8) Heterodimer Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Biotinylated Human Integrin alpha V beta 8 (ITGAV&ITGB8) Heterodimer Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.
It contains Phe31-Val992(ITGAV) acidic tail & Glu43-Arg684(ITGB8) basic tail [Accession | P06756-1(ITGAV)&P26012-1(ITGB8)].

分子量大小(Molecular Weight)

The protein has a predicted MW of 114 kDa (ITGAV)&76 kDa (ITGB8) kDa. Due to glycosylation, the protein migrates to 85-145 kDa based on Bis-Tris PAGE result.

纯度(Purity)

> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC

内毒素(Endotoxin)

Less than 1EU per μg by the LAL method.

制剂(Formulation)

Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

存储(Storage)

-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

产品数据(Assay Data)
Bis-Tris PAGE

Biotinylated Human Integrin alpha V beta 8 (ITGAV&ITGB8) Heterodimer on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.

SEC-HPLC

The purity of Biotinylated Human Integrin alpha V beta 8 (ITGAV&ITGB8) Heterodimer is greater than 95% as determined by SEC-HPLC.

ELISA Data

Immobilized Human Latent TGF beta 1, His Tag at 5μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Human ITGAV&ITGB8, His Tag with the EC50 of 9.62ug/ml determined by ELISA.

背景(Background)

Deletions of the genes encoding the integrin αVβ8 (Itgav, Itgb8) have been shown to result in abnormal vascular development in the CNS, including prenatal and perinatal hemorrhage. Other work has indicated that a major function of this integrin in vivo is to promote TGFβ activation.

分子别名(Synonyms)

αVβ8; Integrin alpha V beta 8; TGAV&ITGB8;Integrin alpha V β 8

Note: HPLC results always come from liquid protein, due to absorption peak interference of trehalose in lyophilized powder.
