Our Abpromise guarantee covers the use of ab9561 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 11 kDa (predicted molecular weight: 11 kDa). To detect hPF-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 hPF-4 is 1.5 - 3.0 ng/lane, under either reducing or non-reducing conditions.|
|ELISA||Use at an assay dependent concentration. To detect hPF-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 of 0.2 - 0.4 ng/well of recombinant hPF-4.|
|Neutralising||Use at an assay dependent concentration. To yield one-half maximal inhibition [ND50] of the biological activity of hPF-4 (50 ng/ml), a concentration of 1.75 - 3.0 µg/ml of this antibody is required.|
|Sandwich ELISA||Use at an assay dependent concentration. Can be paired for Sandwich ELISA with Rabbit polyclonal to PF4 (Biotin) (ab83123).
Can be paired for Sandwich ELISA with ab83123
FunctionReleased during platelet aggregation. Neutralizes the anticoagulant effect of heparin because it binds more strongly to heparin than to the chondroitin-4-sulfate chains of the carrier molecule. Chemotactic for neutrophils and monocytes. Inhibits endothelial cell proliferation, the short form is a more potent inhibitor than the longer form.
Sequence similaritiesBelongs to the intercrine alpha (chemokine CxC) family.
modificationsBinds non-covalently to a proteoglycan molecule.
