Human TACI / TNFRSF13B Protein, His Tag

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.

This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 20.5 kDa. The protein migrates as 19-22 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

● -20°C to -70°C for 12 months in lyophilized state; ● -70°C for 3 months under sterile conditions after reconstitution. For long term storage, the product should be stored at lyophilized state at -20°C or lower.

Immobilized Human BAFF, Fc Tag, active trimer (Cat. No. BAF-H5261) at 2 μg/mL (100 μL/well) can bind Human TACI, His Tag (Cat. No. TAI-H52H3) with a linear range of 1-16 ng/mL (QC tested).
