Highly pure (>98%) recombinant hIL-4 (human Interleukin-4)
Our Abpromise guarantee covers the use of ab9622 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||Use at an assay dependent concentration. Detects a band of approximately 15 kDa. To detect hIL-4 by Western Blot analysis this antibody can be used at a concentration of 0.1 - 0.2 µg/ml. Used in conjunction with compatible secondary reagents the detection limit for recombinant hIL-4 is 1.5 - 3.0 ng/lane, under either reducing or non-reducing conditions. Detects a band of approximately 15 kDa.|
|ELISA||Use at an assay dependent concentration. To detect hIL-4 by direct ELISA (using 100µl/well antibody solution) a concentration of at least 0.5µg/ml of this antibody is required. This antigen affinity purified antibody, in conjunction with compatible secondary reagents, allows the detection.|
|Neutralising||Use at an assay dependent concentration. To yield one-half maximal inhibition [ND50] of the biological activity of hIL-4 (1.50 ng/ml), a concentration of 0.03 - 0.05 µg/ml of this antibody is required.|
|IHC-P||Use a concentration of 0.25 µg/ml.|
|Sandwich ELISA||Use at an assay dependent concentration. Can be used as Detection antibody with recommended pair.|
ab9622 staining IL4 in human breast invasive ductal carcinoma section by Immunohistochemistry (Formalin/PFA fixed paraffin-embedded sections). Tissue underwent heat mediated antigen retrieval in sodium citrate buffer (pH 6.0). The primary antibody was used at 0.25 ug/ml and incubated with sample at 4°C overnight. A HRP-labeled polymer detection system was used with a DAB chromogen. Additional protein blocks were used in conjuction with secondary reagents.
