Lab

Immunocytochemistry/ Immunofluorescence - Anti-GDF11 + GDF8/Myostatin antibody [EPR4567(2)] - BSA and Azide free (AB187407)

Immunocytochemistry/Immunofluorescence analysis of A549 cells labelling BMP11 + GDF8/Myostatin with purified ab124721 at 1/250. Cells were fixed with 4% paraformaldehyde and permeabilized with 0.1% triton X-100. ab150078, an Alexa Fluor^® 555-conjugated goat anti-rabbit IgG (1/500) was used as the secondary antibody. DAPI (blue) was used as the nuclear counterstain.

Control : primary antibody (1/250) and secondary antibody, ab150113, an Alexa Fluor^® 488-conjugated goat anti-mouse IgG (1/500).

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab124721).

Flow Cytometry (Intracellular) - Anti-GDF11 + GDF8/Myostatin antibody [EPR4567(2)] - BSA and Azide free (AB187407)

ab124721 staining GDF11 + GDF8/Myostatin in the human cell line HeLa (human cervix adenocarcinoma) by intracellular flow cytometry. Cells were fixed with 4% paraformaldehyde, permabilised with 90% methanol and the sample was incubated with the primary antibody at a dilution of 1/250. A goat anti rabbit IgG (Alexa Fluor^® 488) at a dilution of 1/2000 was used as the secondary antibody.

Isoytype control : Rabbit monoclonal IgG (Black)

Unlabelled control : Cell without incubation with primary antibody and secondary antibody (Blue)

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab124721).

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human cerebral cortex tissue labelling BMP11 + GDF8/Myostatin with purified ab124721 at 1/2500. Heat mediated antigen retrieval was performed using Tris/EDTA buffer pH 9. A prediluted HRP-polymer conjugated anti-rabbit IgG was used as the secondary antibody. Negative control using PBS instead of primary antibody. Counterstained with hematoxylin.

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.
