分子别名(Synonym)

CD258 antigen,CD258,HVEM-L,LIGHT,LTg,TNFSF14,TR2,HVEML

表达区间及表达系统(Source)

Human LIGHT, Fc tag (LIT-H5265) is expressed from human 293 cells (HEK293). It contains AA Asp 74 - Val 240 (Accession # O43557-1).

Predicted N-terminus: Pro

蛋白结构(Molecular Characterization)

Online(Asp 74 - Val 240) O43557-1

This protein carries a human IgG1 Fc tag at the N-terminus.

The protein has a calculated MW of 44.7 kDa. The protein migrates as 50 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)

>85% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

电泳(SDS-PAGE)

Human LIGHT, Fc tag (Cat. No. LIT-H5265) SDS-PAGE gel

Human LIGHT, Fc tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 85%.

 

活性(Bioactivity)-ELISA

Biotinylated Human ELISA

Immobilized Human HVEM, His Tag (Cat. No. HVM-H52E9) at 5 μg/mL (100 μL/well) can bind Human LIGHT, Fc tag (Cat. No. LIT-H5265) with a linear range of 0.5-8 ng/mL (QC tested).

Protocol

背景(Background)

Tumor necrosis factor ligand superfamily member 14(LIGHT) is a tumor necrosis factor (TNF) superfamily ligand that regulates T cell immune responses by signaling through the herpes virus entry mediator (HVEM) and the lymphotoxin beta receptor (LTbetaR). LIGHT has emerged as a potent initiator of T cell co-stimulation signals effecting CTL-mediated tumor rejection, allograft rejection and graft versus host disease. Constitutive expression of LIGHT leads to tissue destruction and autoimmune-like disease syndromes.
