For research purposes only
Guaranteed for 3 months from the date of reconstitution or until the date of expiry, whichever comes first. Please see label for expiry date.

Prior to reconstitution store at -20oC. Following reconstitution store at -20oC if preferred.

This product should be stored undiluted.

Storage in frost free freezers is not recommended. Avoid repeated freezing and thawing as this may denature the protein. Should this product contain a precipitate we recommend microcentrifugation before use.

This product has been reported to work in the following applications. This information is derived from testing within our laboratories, peer-reviewed publications or personal communications from the originators.

Application Name Verified Min Dilution Max Dilution
ELISA 0.2 0.4ng/well
Functional Assays 0.5 25ng/ml
Western Blotting 1.5 3.0ng/lane
Where this protein has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the protein for use in their own system using appropriate postive/negative controls.
Recombinant human EGF may be used as athe standard in ELISA applications with either a purified human EGF antibody (AHP767) or a biotinylated human EGF antibody (AHP767B).
Western Blotting
Recombinant human EGF may be used as the positive control for Wester Blotting application with either a purified human EGF antibody (AHP767) or a biotinylated human EGF antibody (AHP767B)
