Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-MSH2 antibody [EPR21017-123] - BSA and Azide free (AB228334)

Immunohistochemical analysis of paraffin-embedded human testis tissue labeling MSH2 with ab227941 at 1/8000 dilution, followed by a ready to use Goat Anti-Rabbit IgG H&L (HRP). Nuclear staining in human testis was observed (PMID : 10029069). Counter stained with Hematoxylin.

Secondary antibody only control : Used PBS instead of primary antibody, secondary antibody is a ready to use Goat Anti-Rabbit IgG H&L (HRP).

Perform heat mediated antigen retrieval using ab93684 (Tris/EDTA buffer, pH 9.0).

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab227941).

Overlay histogram showing HAP1 wildtype (green line) and HAP1-MSH2 knockout cells (red line) stained with ab227941. The cells were fixed with 80% methanol (5 min) (left panel) or 4% formaldehyde (10 min) (right panel) , and then permeabilized with 0.1% PBS-Triton X-100 for 15 min. The cells were then incubated in 1x PBS / 10% normal goat serum to block non-specific protein-protein interactions followed by ab227941 for 30 min at 22°C. The secondary antibody used was Alexa Fluor^®488 goat anti-rabbit IgG (H&L) presorbed (ab150081) at 1/2000 dilution for 30 min at 22°C.

A rabbit IgG isotype control antibody (ab172730) was used at the same concentration and conditions as the primary antibody (HAP1 wildtype - black line, HAP1-MSH2 knockout - grey line). Unlabelled sample was also used as a control (this line is not shown for the purpose of simplicity).

Acquisition of >5,000 events were collected using a 50 mW Blue laser (488nm) and 530/30 bandpass filter.

Note : We recommend fixing cells using MeOHinstead of PFA toget optimal results.
