Mouse HTR3B Recombinant Protein (N-His) is a recombinant protein expressed in E. coli, spanning Gln22-Tyr238, with an N-terminal His tag. Predicted molecular weight: 27.53 kDa. Purity: >90% as determined by SDS-PAGE. Supplied lyophilized from a solution in PBS pH 7.4, 1 mM EDTA, 4% Trehalose, 1% Mannitol. Applications: ELISA, immunogen, SDS-PAGE and Western blot. 5-hydroxytryptamine receptor 3B is a ~50 kDa protein. Forms serotonin (5-hydroxytryptamine/5-HT3)-activated cation-selective channel complexes, which when activated cause fast, depolarizing responses in neurons. For research use only.
