特徴

• Lipoprotein-associated phospholipase A2 (Lp-PLA2) also known as platelet-activating factor acetylhydrolase (PAF-AH) is a phospholipase A2 enzyme that in humans is encoded by the PLA2G7 gene.[1][2] Lp-PLA2 is a 45kD protein of 441 amino acids.[3] It is one of several PAF acetylhydrolases. In the blood it travels mainly with low-density lipoprotein (LDL). Less than 20% is associated with high-density lipoprotein HDL. It is an enzyme produced by inflammatory cells and hydrolyzes oxidized phospholipids in LDL. Lp-PLA2 is platelet-activating factor (PAF) acetylhydrolase (EC 3.1.1.47), a secreted enzyme that catalyzes the degradation of PAF to inactive products by hydrolysis of the acetyl group at the sn-2 position, producing the biologically inactive products LYSO-PAF and acetate.[4] Lp-PLA2 is involved in the development of atherosclerosis,[3] an observation that has prompted interest as a possible therapeutic target (see, e.g. the investigational drug Darapladib). In human atherosclerotic lesions, 2 main sources of Lp-PLA2 can be identified, including that which is brought into the intima bound to LDL (from the circulation), and that which is synthesized de novo by plaque inflammatory cells (macrophages, T cells, mast cells).

• Epitope Tag:N-terminal His-Tag
• Molecular Weight:50.0kD
• Applications:Suitable for use in ELISA, Western Blot, Immunoprecipitation, SDS-PAGE
• Other applications not tested.
• Recommended Dilution:Optimal dilutions to be determined by the researcher.
• Storage and Stability:May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -80°C. Aliquots are stable for at least 12 months from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
• Note:Thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation by incubating the protein at 37°C for 48h, with no obvious degradation or precipitation observed. Protein loss is <5% within the expiration date under appropriate storage conditions.
