Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
3-7 business days
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Boost your research in signal transduction with our premium-quality Recombinant Human ASGR1 protein. Asialoglycoprotein receptor 1 (ASGR1) is a C-type lectin and a key component of the asialoglycoprotein receptor, which plays a critical role in the clearance of desialylated glycoproteins from the blood circulation. ASGR1-mediated endocytosis is essential in maintaining the proper turnover of serum glycoproteins and contributes to hepatic homeostasis.

Sourced from E. coli expression systems, our recombinant ASGR1 protein encompasses a partial 68-291aa region, thoughtfully engineered for optimal research performance. The N-terminal 6xHis-tag ensures streamlined protein purification, while the impressive purity (>90% as determined by SDS-PAGE) guarantees reliable results in your experiments. Provided as a lyophilized powder, our Recombinant Human ASGR1 protein is ready to empower your signal transduction research.

Would you tell us if CSB-RP174694h contains materials of human or monkey origin?
Would you also tell us If the materials are derived from human or monkey cell lines (such as HEK293)?

Thanks for your inquiry.
1. This protein does not contain any material of human or monkey origin.
2. This protein is expressed in E. coli expression system, not in Mammalian cell (such as HEK293).

Target Background

Mediates the endocytosis of plasma glycoproteins to which the terminal sialic acid residue on their complex carbohydrate moieties has been removed. The receptor recognizes terminal galactose and N-acetylgalactosamine units. After ligand binding to the receptor, the resulting complex is internalized and transported to a sorting organelle, where receptor and ligand are disassociated. The receptor then returns to the cell membrane surface.

  1. Authors report the generation of a human embryonic stem cell line WAe001-A-6 harbouring homozygous ASGR1 mutations using CRISPR/Cas9. The mutation involves a 37bp deletion, resulting in a frame shift. PMID: 28952928
  2. PEGylated lipoplexes were well tolerated by both HEK293 (ASGP-R-negative) and HepG2 (ASGP-R-positive) cell lines and delivered DNA to the hepatoma cell line HepG2 by ASGP-R mediation at levels three-fold greater than nonPEGylated lipoplexes. PMID: 28063265
  3. findings show that the hepatitis E virus (HEV) ORF2 protein interacts directly with the ectodomain of both ASGR1 and ASGR2; ASGPR is involved in and facilitates HEV infection by binding to ORF2 PMID: 27155063
  4. ASGR1 can inhibit the activity of V-ATPase by interacting with LASS2, thereby suppressing the metastatic potential of hepatoma cells. PMID: 27241665
  5. This review will focus on the mechanisms of platelet senescence with specific emphasis on the role of post-translational modifications in platelet life-span and thrombopoietin production downstream of the hepatic Ashwell-Morrell receptor, originally termed asialoglycoprotein receptor (ASGPR). PMID: 27207430
  6. ASGR1 haploinsufficiency was associated with reduced levels of non-HDL cholesterol and a reduced risk of coronary artery disease. PMID: 27192541
  7. Flow cytometric assessment of ASGPR expression may be a useful predictor of liver dysfunction following major hepatectomy for HCC in Chinese patients. PMID: 25404440
  8. Anti-ASGPR antibody could be used for specific and efficient HCC CTC enrichment, and anti-P-CK combined with anti-CPS1 antibodies is superior to identification with one antibody alone in the sensitivity for HCC CTC detection. PMID: 24763545
  9. Endocytic AMR controls TPO expression through Janus kinase 2 (JAK2) and the acute phase response signal transducer and activator of transcription 3 (STAT3) in vivo and in vitro PMID: 25485912

  11. The examined ASGPR1 expression levels by immunohistochemistry in HCC with different grades. Guidance for a targeting delivery strategy for anti-cancer drugs to HCC is suggested in this report. PMID: 23979840
  12. the distribution of ASGR in human testis, was investigated. PMID: 23604802
  13. the cooperative binding mode of Ca(2+) makes it possible for ASGP-R to be more sensitive to Ca(2+) concentrations in early endosomes, and plays an important role in the efficient release of ligand from ASGP-R PMID: 22613667
  14. Constant sH2a levels suggest constitutive secretion from hepatocytes in healthy individuals; therefore, a decrease with cirrhosis suggests a diagnostic potential. PMID: 22219600

  17. Two naturally occurring ASGPR1 splice variants are produced in human hepatocytes. PMID: 20886072
  18. our findings suggest that both fibronectin and ASGPR mediate HBsAg binding to the cell surface, which provides further evidence for the potential roles of these two proteins in mediating HBV binding to liver cells. PMID: 20364278
  19. The minor subunit splice variants, H2b and H2c, of the human asialoglycoprotein receptor are present with the major subunit H1 in different hetero-oligomeric receptor complexes PMID: 11943787
