Ready-to-use ELISA kits are available for the detection of inter-alpha trypsin inhibitor, heavy chain 2, an alias of the protein, inter-alpha-trypsin inhibitor heavy chain 2. The official gene symbol is ITIH2. The protein, with a mass of 106.5 kDa and length of 946 residues, is reported to be secreted. It is a member of the ITIH family and may be known by other names, including: inter-alpha-trypsin inhibitor complex component II, inter-alpha-inhibitor heavy chain 2, inter-alpha (globulin) inhibitor H2, ITI-HC2, ITI heavy chain H2, and inter-alpha-trypsin inhibitor heavy chain H2.
