Applications and Data

 Recommended
Concentration
Sample
Western Blot0.2 µg/mLSee below
Blockade of Receptor-ligand InteractionIn a functional ELISA, 0.5-2 µg/mL of this antibody will block 50% of the binding of 400 ng/mL of biotinylated AGE-BSA to immobilized Recombinant Human SR-AI/MSR (Catalog # 2708-MS) coated at 5 µg/mL (100 µL/well). At 20 μg/mL, this antibody will block >90% of the binding.
Immunocytochemistry1-15 µg/mLSee below


Western Blot
Detection of Human SR‑AI/MSR by Western Blot.
Western blot shows lysates of THP‑1 human acute monocytic leukemia cell line untreated (-) or treated (+) with PMA. PVDF membrane was probed with 0.2 µg/mL of Goat Anti-Human SR‑AI/MSR Antigen Affinity-purified Polyclonal Antibody(Catalog # AF2708) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for SR‑AI/MSR at approximately 80 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Immunocytochemistry
SR‑AI/MSR in THP-1 Human Cell Line.
SR‑AI/MSR was detected in immersion fixed THP‑1 human acute monocytic leukemia cell line untreated (right panel) and treated with PMA (left panel) using Goat Anti-Human SR‑AI/MSR Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2708) at 1.7 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

background_contentBackground:
SR-AI/MSR
The type I class A macrophage scavenger receptor (SR-AI; also MSR-AI) is a 70-80 kDa protein that belongs to an ever expanding family of transmembrane molecules collectively referred to as scavenger receptors (1-3). Receptors of this family contain characteristic extracellular domains and bind to a series of generally unrelated, but negatively-charged/polyanionic ligands (1, 3). Human SR-AI is a type II transmembrane glycoprotein that is 451 amino acids (aa) in length. It contains a 50 aa cytoplasmic tail, a 26 aa transmembrane segment and a 375 aa extracellular region (4, 5). The extracellular region contains four definitive domains, with a membrane proximal spacer of 33 aa, an alpha -helical coiled-coil domain of 163 aa, a collagen-like domain of 69 aa, and a cysteine-rich C-terminus of 110 aa (4, 6). The cysteine-rich domain (CRD) forms three intrachain disulfide bonds (7). The functional form of the molecule is a 220-230 kDa membrane-associated trimer that, in human, apparently has two disulfide bonded chains and a third noncovalently associated subunit (8, 9). Human extracellular region is 73% and 72% aa identical to bovine and mouse SR-AI extracellular region, respectively. The human gene for SR-A gives rise to three isoforms; the I isoform of 451 aa, the II isoform of 358 aa, and the III isoform of 388 aa (4, 5, 10). All are equal through the first 344 aa which includes the cytoplasmic tail through the collagenous domain. Isoform II (SR-AII) shows a severe truncation of the CRD, but is expressed on the cell surface. Isoform III (SR-AIII) has a modest truncation of the CRD, and cannot be expressed on the cell surface. Their functions are unknown. However, relative to SR-AI, SR-AII is known to show differential sensitivity to LPS and receptor binding to gram-negative bacteria (9, 11), while SR-AIII is known to be a dominant-negative isoform (10). SR-AIII may achieve this by either heterotrimerizing with SR-AI, or simply eliminating the production of SR-AI mRNA.
