Active Recombinant Human LDLR protein, His-tagged

• Cat.No.: LDLR-798H
• Product Overview: Active Recombinant Human LDLR protein(NP_000518.1)(Met 1-Arg 788) was expressed in HEK293 with a C-terminal polyhistidine tag.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 1-788 aa
• Form: Lyophilized from sterile PBS, pH 7.4.
• Bio-activity: 1. Measure by its ability to bind with human PCSK9 in a functional ELISA. Immobilized human PCSK9 at 10 μg/ml (100 μl/well) can bind biotinylated recombinant human LDLR. The EC50 of biotinylated human LDLR is 0.61 μg/ml. 2. Immobilized mouse PCSK9 at 10 μg/ml (100 μl/well) can bind biotinylated recombinant human LDLR. The EC50 of biotinylated human LDLR is 0.12 μg/ml.
• Molecular Mass: The secreted recombinant human LDLR comprises 777 amino acids with a predicted molecular mass of 86 kDa. As a result of different glycosylation, it migarates with the apparent molecular mass of 110-140 kDa in SDS-PAGE under reducing conditions corresponding to the mature and immature form.
• Endotoxin: < 1 EU/µg as determined by LAL test.
• Purity: > 85 % as determined by SDS-PAGE
• Storage: Store it under sterile conditions at -20°C to -80°C upon receiving. Recommend to aliquot the protein into smaller quantities 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°C before opening to recover the entire contents.
