Source

Human TSPAN8, His Tag (TS8-H52H3) is expressed from human 293 cells (HEK293). It contains AA Lys 110 - Asn 205 (Accession # P19075-1).

Predicted N-terminus: His

Molecular Characterization
Other Tags and Version Biotin & Other Labeled Version

This protein carries a polyhistidine tag at the N-terminus.

The protein has a calculated MW of 12.9 kDa. The protein migrates as 14 kDa and 17-19 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 0.01 EU per μg by the LAL method / rFC method.

Purity

>90% as determined by SDS-PAGE.

>95% as determined by SEC-MALS.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Introduction de fond

Tspan8 is 1 of the 33 mammalian members of the tetraspanin family, composed of transmembrane proteins that organize laterally, together or with other membrane partners such as integrins, to form ‘tetraspanin webs’. These platforms signal within cells to regulate many cellular processes: adhesion, migration, invasion or survival Tspan8 has been implicated in many types of cancer.Overexpression was reported in glioma and colorectal, esophageal, hepatic, gastric and pancreatic carcinoma. Tspan8 exerts a pro-invasive function by controlling cell–cell and cell–matrix interactions through its association with membrane partners such as α6β4 integrin-protein kinase C (PKC)-activated, E-cadherin, EpCAM, claudin-7 and CD44. Moreover, Tspan8 may be a promising new therapeutic target, as Tspan8-specific antibodies were shown to reduce cell motility, block tumor angiogenesis in vivo.
