Ready-to-use ELISA kits are available for the detection of lpd1, an alias of the protein, lipase H. The official gene symbol is LIPH. The kits can detect several species variants of the protein, including: human, mouse, rat, chicken, primate, guinea pig, and other mammalian. The protein, with a mass of 50.9 kDa and length of 451 residues, is reported to be secreted. It is a member of the AB hydrolase superfamily, Lipase family and may be known by other names, including: phospholipase A(1), membrane-bound phosphatidic acid-selective phospholipase A1, mPA-PLA1 alpha, lipase member H, LPD lipase-related protein, and lipase member H, and AH.
