Ready-to-use ELISA kits are available for the detection of SHARP1, an alias of the protein, basic helix-loop-helix family member e41. The official gene symbol is BHLHE41. The kits can detect several species variants of the protein, including: bovine and other mammalian. The protein, with a mass of 50.5 kDa and length of 482 residues, is reported to be nuclear. It may be known by other names, including: SHARP1, 43801, enhancer-of-split and hairy-related protein 1, differentially expressed in chondrocytes protein 2, basic helix-loop-helix domain containing class B 3, and class E basic helix-loop-helix protein 41.
