Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Cytochrome P450 3A4/CYP3A4 antibody [EPR6202] - BSA and Azide free (AB245774)

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of Human liver tissue sections labeling Cytochrome P450 3A4/CYP3A4 with purified ab124921 at 1/400 dilution (0.35 μg/ml). Perform heat mediated antigen retrieval using ab93684 (Tris/EDTA buffer, pH 9.0). ImmunoHistoProbe one step HRP Polymer (ready to use) was used as the secondary antibody. Negative control : PBS instead of the primary antibody. Hematoxylin was used as a counterstain.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab124921).

Western blot - Anti-Cytochrome P450 3A4/CYP3A4 antibody [EPR6202] - BSA and Azide free (AB245774)

HepG2 cells were incubated at 37°C for 48h with vehicle control (0 μM) and different concentrations of nicardipine hydrochloride (ab120531) in DMSO. Increased expression of Cytochrome P450 3A4/CYP3A4 (ab124921) correlates with an increase in nicardipine hydrochloride concentration, as described in literature. Whole cell lysates were prepared with RIPA buffer (containing protease inhibitors and sodium orthovanadate), 10μg of each were loaded on the gel and the WB was run under reducing conditions. After transfer the membrane was blocked for an hour using 5% BSA before being incubated with ab124921 at 1/10000 dilution and ab9484 at 1 μg /ml overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP (ab97051) at 1/10000 dilution and visualised using ECL development solution. This data was developed using the same antibody clone in a different buffer formulation containing Tris glycine, glycerol and sodium azide (ab124921).

Blocking and diluting buffer and concentration : 5% NFDM/TBST.

ab205606 was used as a tag loading control.

The detection of CYP3A4 recombinant protein or over -expressed protein with a C - terminal tag yielded a negative result because the immunogen of this product is located at the C - terminal of CYP3A4.

We have systematically measured KD (the equilibrium dissociation constant between the antibody and its antigen) of more than 840 recombinant antibodies to assess not only their individual KD values but also to see the average affinity of antibody. Based on the comparison with published literature values for mouse monoclonal antibodies Recombinant antibodies appear to be on average 1-2 order of magnitude higher affinity.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol and sodium azide (ab124921).
