Human TACI / TNFRSF13B Protein, His Tag

分子别名(Synonym)

CD267,TACI,TNFRSF13B

表达区间及表达系统(Source)

Human TACI, His Tag (TAI-H52H3) is expressed from human 293 cells (HEK293). It contains AA Ser 2 - Thr 166 (Accession # O14836-1).

蛋白结构(Molecular Characterization)

Online(Ser 2 - Thr 166) O14836-1

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

The protein has a calculated MW of 20.5 kDa. The protein migrates as 20-22 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>90% as determined by reduced SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

背景(Background)

Transmembrane activator and CAML interactor (TACI), also known as tumor necrosis factor receptor superfamily member 13B (TNFRSF13B). It was originally discovered because of its ability to interact with calcium-modulator and cyclophilin ligand (CAML). TACI was later found to play a crucial role in humoral immunity by interacting with two members of the TNF family: BAFF and APRIL. The present study demonstrated that, in NSCLC, a proliferation-inducing ligand (APRIL), B-cell maturation antigen (BCMA)and transmembrane activator and CAML interactor (TACI) proteins are abnormally expressed by immunohistochemistry, reverse transcription-quantitative polymerase chain reaction and western blotting. In addition, the expression of APRIL, BCMA and TACI were observed to be involved in extracellular signal-regulated kinase (ERK)1/2 activation in A549 cells.
