Recombinant Human MSR1 Protein, His-tagged

• Cat.No.: MSR1-2026H
• Product Overview: Recombinant Human SR-AI/MSR1 Protein is produced by HEK293 expression system. The target protein is expressed with sequence (Lys77-Leu451) of human SR-AI/MSR1 (Accession #NP_619729.1) fused with a 6×His tag at the C-terminus.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: Lys77-Leu451
• Description: This gene encodes the class A macrophage scavenger receptors, which include three different types (1, 2, 3) generated by alternative splicing of this gene. These receptors or isoforms are macrophage-specific trimeric integral membrane glycoproteins and have been implicated in many macrophage-associated physiological and pathological processes including atherosclerosis, Alzheimer's disease, and host defense. The isoforms type 1 and type 2 are functional receptors and are able to mediate the endocytosis of modified low density lipoproteins (LDLs). The isoform type 3 does not internalize modified LDL (acetyl-LDL) despite having the domain shown to mediate this function in the types 1 and 2 isoforms. It has an altered intracellular processing and is trapped within the endoplasmic reticulum, making it unable to perform endocytosis. The isoform type 3 can inhibit the function of isoforms type 1 and type 2 when co-expressed, indicating a dominant negative effect and suggesting a mechanism for regulation of scavenger receptor activity in macrophages.
• Form: Lyophilized from sterile PBS, pH 7.4, 5 % trehalose, 5 % mannitol.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: > 90% as determined by SDS-PAGE
• Stability: Samples are stable for up to twelve months from date of receipt at -70ºC.
• Storage: Store it under sterile conditions at -20ºC~-70ºC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
