  • 产品描述：

    The DNA sequence coming from the PCSK9 monoclonal antibody produced from the synthesized human PCSK9 peptide immunization was cloned into the expression vector, which was further transfected into a cell line for in vitro expression. The product is the recombinant PCSK9 monoclonal antibody. It specifically targets the PCSK9 from human. It belongs to the rabbit IgG. The affinity-chromatography purification method was used to purify this PCSK9 antibody. The ELISA, WB, and IHC analyses have been tested for this PCSK9 antibody.

    The dyslipidemia treatment based on PCSK9 monoclonal antibodies is currently recommended to achieve risk-specific low-density lipoprotein cholesterol (LDL-C) goal to reduce adverse cardiovascular (CV) events. Two fully human anti-PCSK9 antibodies evolocumab and alirocumab developed by transgenic mice platforms have been approved for hypercholesterolemia treatment in the clinical.

  • 功能：
    Crucial player in the regulation of plasma cholesterol homeostasis. Binds to low-density lipid receptor family members: low density lipoprotein receptor (LDLR), very low density lipoprotein receptor (VLDLR), apolipoprotein E receptor (LRP1/APOER) and apolipoprotein receptor 2 (LRP8/APOER2), and promotes their degradation in intracellular acidic compartments. Acts via a non-proteolytic mechanism to enhance the degradation of the hepatic LDLR through a clathrin LDLRAP1/ARH-mediated pathway. May prevent the recycling of LDLR from endosomes to the cell surface or direct it to lysosomes for degradation. Can induce ubiquitination of LDLR leading to its subsequent degradation. Inhibits intracellular degradation of APOB via the autophagosome/lysosome pathway in a LDLR-independent manner. Involved in the disposal of non-acetylated intermediates of BACE1 in the early secretory pathway. Inhibits epithelial Na(+) channel (ENaC)-mediated Na(+) absorption by reducing ENaC surface expression primarily by increasing its proteasomal degradation. Regulates neuronal apoptosis via modulation of LRP8/APOER2 levels and related anti-apoptotic signaling pathways.
