- GRP-78 Escherichia Hsp-5 TNF? anticitrullinated preimmunization auto-immune noncitrullinated nonimmunized
- Product Overview:
Glucose-regulated protein 78 kDa (GRP78) is a molecular chaperone that is ubiquitously expressed in the endoplasmic reticulum of mammalian cells.{36130,36131,36132} GRP78 can be citrullinated at its 27 arginine residues by protein deiminases (PADs).{37332} The accumulation of citrullinated proteins in vivo leads to the production of anti-citrullinated protein antibodies (ACPAs) which perpetuate the inflammatory process.{32067} In vitro, ACPAs bind to citrullinated GRP78 expressed on the cell surface of peripheral blood mononuclear cells PMBCs and U937 cells leading to the production of TNF-?.{37330,37331} In a mouse model of collagen-induced arthritis (CIA), anti-citrullinated GRP78 antibodies are found in the serum.{37332} Pre-immunization with citrullinated GRP78 prior to CIA induction shortens the time to joint inflammation and increases arthritis scores compared with non-citrullinated GRP78-immunized and non-immunized control mice. In autoimmune diseases such as rheumatoid arthritis, patient-derived serum contains higher levels of anti-citrullinated GRP78 antibodies than serum derived from patients with systemic lupus erythematosus and healthy controls.{37332}
Cayman Chemical’s mission is to help make research possible by supplying scientists worldwide with the basic research tools necessary for advancing human and animal health. Our utmost commitment to healthcare researchers is to offer the highest quality products with an affordable pricing policy.
Our scientists are experts in the synthesis, purification, and characterization of biochemicals ranging from small drug-like heterocycles to complex biolipids, fatty acids, and many others. We are also highly skilled in all aspects of assay and antibody development, protein expression, crystallization, and structure determination.
Over the past thirty years, Cayman developed a deep knowledge base in lipid biochemistry, including research involving the arachidonic acid cascade, inositol phosphates, and cannabinoids. This knowledge enabled the production of reagents of exceptional quality for cancer, oxidative injury, epigenetics, neuroscience, inflammation, metabolism, and many additional lines of research.
Our organic and analytical chemists specialize in the rapid development of manufacturing processes and analytical methods to carry out clinical and commercial GMP-API production. Pre-clinical drug discovery efforts are currently underway in the areas of bone restoration and repair, muscular dystrophy, oncology, and inflammation. A separate group of Ph.D.-level scientists are dedicated to offering Hit-to-Lead Discovery and Profiling Services for epigenetic targets. Our knowledgeable chemists can be contracted to perform complete sample analysis for analytes measured by the majority of our assays. We also offer a wide range of analytical services using LC-MS/MS, HPLC, GC, and many other techniques.
