ICOSLG Protein (AA 29-450) (His tag)

Catalog No. ABIN6253382

Product Details

Target: ICOSLG (Inducible T-Cell Co-Stimulator Ligand (ICOSLG))

Protein Type: Recombinant

Protein Characteristics: AA 29-450

Origin: Human

Source: HEK-293 Cells

Purification tag / Conjugate: This ICOSLG protein is labelled with His tag.

Purpose: CD275 [B7-H2] (human) (rec.) (His)

Specificity: The extracellular domain of human CD275 [B7-H2] (aa 19-256) is fused at the C-terminus to a His-tag.

Characteristics: Protein. The extracellular domain of human CD275 [B7-H2] (aa 19-256) is fused at the C-terminus to a His-tag. Source: HEK 293 cells. Endotoxin content: <0.01EU/μg protein (LAL test, Lonza). Lyophilized from 0.2μm-filtered solution in PBS. Purity: >95 % (SDS-PAGE). Human B7-H2 is a member of the growing B7 family of immune costimulatory proteins. Other family members include B7-1, B7-2, B7-H1 (PD-L1), PD-L2 and B7-H3. B7 proteins are members of the immunoglobulin (Ig) superfamily, the extracellular domains contain 2 Ig-like domains and all members have short cytoplasmic domains. B7-H2 has been identified as the ligand for ICOS, a member of the CD28 family of costimulatory receptors. Human B7-H2 is expressed constitutively on resting B cells, dendritic cells and at low levels on monocytes. The B7-H2/ICOS interaction appears to play roles in T cell dependent B cell activation and Th differentiation.

Purity: >95 % (SDS-PAGE)
