Human TACI / TNFRSF13B (R119A, R122A) Protein, Fc Tag (MALS verified)

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 human IgG1 Fc tag at the C-terminus. The protein has a calculated MW of 44.8 kDa. The protein migrates as 50-60 kDa 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, His Tag at 2 μg/mL (100 μL/well) can bind Human TACI (R119A, R122A), Fc Tag (Cat. No. TAI-H5253) with a linear range of 0.2-2 ng/mL (QC tested).
