HOST SPECIES:Rabbit
SPECIES REACTIVITY: Human, Mouse, Rat
HOMOLOGY: Predicted species reactivity based on immunogen sequence: Pig: (93%), Bovine: (80%)
IMMUNOGEN: SCARB1 antibody was raised against a 15 amino acid synthetic peptide near the amino terminus of human SCARB1.

The immunogen is located within amino acids 70 - 120 of SCARB1.
TESTED APPLICATIONS: ELISA, IF, IHC-P, WB
APPLICATIONS: SCARB1 antibody can be used for detection of SCARB1 by Western blot at 1 - 2 μg/mL. Antibody can also be used for immunohistochemistry starting at 2.5 μg/mL. For immunofluorescence start at 20 μg/mL.

Antibody validated: Western Blot in human samples; Immunohistochemistry in human samples and Immunofluorescence in human samples. All other applications and species not yet tested.
SPECIFICITY: At least two isoforms of SCARB1 are known to exist; this antibody can detect both isoforms.

psi-iconBackground and References
BACKGROUND:SCARB1 Antibody: Scavenger receptor class B member 1 (SCARB1), also known as SR-BI, is part of the scavenger receptor superfamily, which is composed of many members with diverse structures, expression patterns, and functions. SCARB1 is a multi-ligand cell-surface receptor that mediates the selective uptake of lipid from HDL cholesterol into cells and is expressed in steroidogenic tissues in adult animals. Other ligands of SCARB1 include native, acetylated, or oxidized LDL and anionic phospholipids. SCARB1-deficient mice have elevated HDL levels and increased susceptibility to atherosclerosis on fat feeding, indicating its importance in the regulation of cholesterol homeostasis. Along with CLDN1, LDL-R, and the tetraspanin superfamily member CD81, SCARB1 has been reported to be an entry factor for the Hepatitis C virus.
