Sam50 (sorting assembly machinery component 50 homolog, S. cerevisiae), also known as SAMM50, OMP85, TOB55, TRG-3, CGI-51 or YNL026W, is a β-barrel multi-pass membrane protein that belongs to the SAM50/omp85 family of proteins. Localizing to the mitochondrion, Sam50 is believed to function in the assembly pathway of mitochondrial outer membrane β-barrel proteins. More specifically, Sam50 functions as the major component of the SAM (sorting and assembly machinery) complex, also known as the TOB (topogenesis of mitochondrial outer membrane β-barrel proteins) complex, and is required for cell viability. Exposed to the intermembrane space (IMS), the N-terminal POTRA (polypeptide transport-associated) domain of Sam50 (a domain that is conserved from bacteria to man) functions like a receptor for β-barrel proteins. The association of the Sam35 subunit of the SAM complex is essential for Sam50 binding to outer membrane substrate proteins.

Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (HA720059) at 1/2,000 dilution was used in 5% NFDM/TBST at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1/50,000 dilution was used for 1 hour at room temperature.
Immunohistochemical analysis of paraffin-embedded human pancreas tissue with Rabbit anti-SAMM50 antibody (HA720059) at 1/1,000 dilution.
The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (HA720059) at 1/1,000 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.
Immunohistochemical analysis of paraffin-embedded human kidney tissue using anti-SAMM50 antibody. The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes.The tissues were blocked in 5% BSA for 30 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (HA720059, 1/200) for 30 minutes at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.
