Source
Human LDL R Protein, premium grade (LDR-H5214) is expressed from human 293 cells (HEK293). It contains AA Ala 22 - Arg 788 (Accession # P01130-1).
Predicted N-terminus: Ala 22
It is produced under our rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. Product performance is carefully validated and tested for compatibility for cell culture use or any other applications in the early preclinical stage. When ready to transition into later clinical phases, we also offer a custom GMP protein service that tailors to your needs. We will work with you to customize and develop a GMP-grade product in accordance with your requests that also meets the requirements for raw and ancillary materials use in cell manufacturing of cell-based therapies.

FAQ
- Product
What key experimental conditions should be considered for PCSK9–LDLR binding assays?
It is recommended to perform PCSK9–LDLR binding assays under acidic conditions, as the interaction exhibits higher activity in acidic environments compared to neutral ones. Reference: Effects of pH and Low Density Lipoprotein (LDL) on PCSK9-dependent LDL Receptor Regulation.
