Validation Data Gallery

• 

  WB analysis using 66866-1-Ig (same clone as 66866-1-PBS)

  Various lysates were subjected to SDS PAGE followed by western blot with 66866-1-Ig (CD81 antibody) at dilution of 1:3000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 66866-1-PBS in a different storage buffer formulation.

• 

  WB analysis using 66866-1-Ig (same clone as 66866-1-PBS)

  HEK-293 cells and HEK-293-derived exosomes (HEK-293-exo) were subjected to SDS PAGE followed by western blot with 66866-1-Ig (CD81 antibody) at dilution of 1:8000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 66866-1-PBS in a different storage buffer formulation.

• 

  WB analysis of Jurkat using 66866-1-Ig (same clone as 66866-1-PBS)

  Jurkat cells were subjected to SDS PAGE followed by western blot with 66866-1-Ig (CD81 antibody) at dilution of 1:3000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 66866-1-PBS in a different storage buffer formulation.

• 

  WB analysis of THP-1 using 66866-1-Ig (same clone as 66866-1-PBS)

  LPS treated THP-1 cells were subjected to SDS PAGE followed by western blot with 66866-1-Ig (CD81 antibody) at dilution of 1:3000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 66866-1-PBS in a different storage buffer formulation.

• 

  IHC staining of human tonsillitis using 66866-1-Ig (same clone as 66866-1-PBS)

  Immunohistochemical analysis of paraffin-embedded human tonsillitis tissue slide using 66866-1-Ig (CD81 antibody) at dilution of 1:1000 (under 10x lens). Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0). This data was developed using the same antibody clone with 66866-1-PBS in a different storage buffer formulation.

• 

  IHC staining of human tonsillitis using 66866-1-Ig (same clone as 66866-1-PBS)

  Immunohistochemical analysis of paraffin-embedded human tonsillitis tissue slide using 66866-1-Ig (CD81 antibody) at dilution of 1:1000 (under 40x lens). Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0). This data was developed using the same antibody clone with 66866-1-PBS in a different storage buffer formulation.

• 

  IF Staining of human tonsillitis using 66866-1-Ig (same clone as 66866-1-PBS)

  Immunofluorescent analysis of (4% PFA) fixed human tonsillitis tissue using CD81 antibody (66866-1-Ig, Clone: 1G2C6 ) at dilution of 1:1000 and CoraLite®488-Conjugated AffiniPure Goat Anti-Mouse IgG(H+L). This data was developed using the same antibody clone with 66866-1-PBS in a different storage buffer formulation.

Background Information

CD81 (also known as TAPA1 or TSPAN28) is a membrane protein of the tetraspanin superfamily, which are characterized by the presence of four conserved transmembrane regions. 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 en essential receptor for HCV (hepatitis C virus) (PMID: 21428934).
