Human TIM-3, also known as T-cell immunoglobulin mucin receptor 3, T-cell membrane protein 3, TIMD-3, Hepatitis A virus cellular receptor 2, HAVCR-2, and KIM- 3. GenBank Accession No. NM_032782, a.a. 22-200 with a C-terminal Avi-biotin, Histag, expressed in a HEK293 cell expression system. MW = 23.3 kDa. This protein is enzymatically biotinylated using Avi-tagTM technology. Biotinylation is confirmed to be greater than 90%. This protein runs at a higher MW by SDS-PAGE due to glycosylation.
