Many of these members are expressed on leukocytes and have been implicated in signal transduction, cell-cell interactions, and cellular activation and development. CD81 is involved in signal transduction and cell adhesion in the immune system (PMID: 9597125). CD81 has also been identified as an essential receptor for HCV (hepatitis C virus) (PMID: 21428934).\n\u003cb\u003eSpecification\u003c\/b\u003e\nTested Reactivity: human, mouse, rat\nCited Reactivity: human, mouse, rat, canine, zebrafish\nHost \/ Isotype: Rabbit \/ IgG\nClass: Polyclonal\nType: Antibody\nImmunogen: CatNo: Ag27298 Product name: Recombinant human CD81 protein Source: e coli. -derived, PET28a Tag: 6*His Domain: 114-199 aa of BC002978 Sequence: VNKDQIAKDVKQFYDQALQQAVVDDDANNAKAVVKTFHETLDCCGSSTLTALTTSVLKNNLCPSGSNIISNLFKEDCHQKIDDLFS Predict reactive species\nFull Name: CD81 molecule\nCalculated Molecular Weight: 26 kDa\nObserved Molecular Weight: 23 kDa\nGenBank Accession Number: BC002978\nGene Symbol: CD81\nGene ID (NCBI): 975\nENSEMBL Gene ID: ENSG00000110651\nRRID: AB_2880995\nConjugate: Unconjugated\nForm: Liquid\nPurification Method: Antigen affinity purification\nUNIPROT ID: P60033\nStorage Buffer: PBS with 0.02% sodium azide and 50% glycerol, pH 7.3.\nStorage Conditions: Store at -20°C.
