Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-SHP1 antibody [EPR5519] - BSA and Azide free (AB240949)

ab124942, at a 1/1000 dilution, staining SHP1 in paraffin-embedded human tonsil tissue by immunohistochemistry.

This data was developed using the same antibody clone in a different buffer formulation containing tissue culture supernatant, PBS, BSA, glycerol, and sodium azide (ab124942)

Immunocytochemistry/ Immunofluorescence - Anti-SHP1 antibody [EPR5519] - BSA and Azide free (AB240949)

Immunocytochemistry/Immunofluorescence analysis of Raji (human Burkitt's lymphoma) cells labeling SHP1 with purified ab124942 at a dilution of 1/500. Cells were fixed with 4% paraformaldehyde and permeabilized with 0.1% Triton X-100. An Alexa-Fluor^® 488-conjugated goat anti-rabbit IgG (ab150077) at dilution of 1/1000 was used as the secondary antibody. Nuclei counterstained with DAPI (blue).

Secondary Only Control : PBS was used instead of the primary antibody as the negative control.

This data was developed using ab124942, the same antibody clone in a different buffer formulation.Intracellular Flow Cytometry analysis of Jurkat (Human T cell leukemia T lymphocyte) cells labeling SHP1 with purified ab124942 at 1/100 dilution (10μg/mL) (Red). Cells were fixed with 4% Paraformaldehyde and permeabilised with 90% Methanol. A Goat anti rabbit IgG (Alexa Fluor^® 488, ab150077) secondary antibody was used at 1/2000. Isotype control - Rabbit monoclonal IgG (Black). Unlabeled control - Cells without incubation with primary antibody and secondary antibody (Blue).

Western blot - Anti-SHP1 antibody [EPR5519] - BSA and Azide free (AB240949)

This data was developed using the same antibody clone in a different buffer formulation (ab124942).

Lanes 1 - 4 : Merged signal (red and green). Green - ab124942 observed at 70 kDa. Red - loading control ab8245 (Mouse anti-GAPDH antibody [6C5]) observed at 37 kDa.

ab124942 was shown to react with SHP1 in wild-type THP-1 cells in Western blot with loss of signal observed in PTPN6 knockout sample. Wild-type THP-1 and PTPN6 knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 3 % milk in TBS-T (0.1 % Tween^®) before incubation with ab124942 and ab8245 (Mouse anti-GAPDH antibody [6C5]) overnight at 4 °C at a 1 in 1000 dilution and a 1 in 20000 dilution respectively. Blots were incubated with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 h at room temperature before imaging.

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.
