Asialoglycoprotein receptor 1 (ASGR1), partial, human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 68-291aa. Protein Length: Partial. Tag Info: N-terminal 6xHis-tagged. Target Protein Sequence: EELRGLRETF SNFTASTEAQ VKGLSTQGGN VGRKMKSLES QLEKQQKDLS EDHSSLLLHV KQFVSDLRSL SCQMAALQGN GSERTCCPVN WVEHERSCYW FSRSGKAWAD ADNYCRLEDA HLVVVTSWEE QKFVQHHIGP VNTWMGLHDQ NGPWKWVDGT DYETGFKNWR PEQPDDWYGH GLGGGEDCAH FTDDGRWNDD VCQRPYRWVC ETELDKASQE PPLL. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: 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. Storage: 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. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Mediates the endocytosis of plasma glycoproteins to which the terminal sialic acid residue on their complex carbohydrate moieties has been roved. 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 mbrane surface.

Proteome Res. 8:651-661(2009). Function: 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.
