Reprobing of an existing membrane is a convenient means to immunoblot for multiple proteins independently when only a limited amount of sample is available. It should be noted that for the best possible results a fresh blot is always recommended. Reprobing can be a valuable method but with each reprobing of a blot there is potential for increased background signal. Additionally, it is recommended that you verify the removal of the first antibody complex prior to reprobing so that signal attributed to binding of the new antibody is not leftover signal from the first immunoblotting experiment. This can be done by re-exposing the blot to ECL reagents and making sure there is no signal prior to adding the next primary antibody.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalently purified water.

XPF (D3G8C) Rabbit mAb recognizes endogenous levels of total XPF (ERCC4) protein.Species Reactivity:
Human, Rat, Monkey
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Arg670 of human XPF (ERCC4) protein.
DNA repair systems operate in all living cells to manage a variety of DNA lesions. Nucleotide excision repair (NER) is implemented in cases where bulky helix-distorting lesions occur, such as those brought about by UV and certain chemicals (1). Excision Repair Cross Complementing 4 (ERCC4, XPF) forms a complex with the ERCC1 excision repair protein to create an essential 5’ endonuclease responsible for lesion excision (2). ERCC1-XPF is also required for repair of DNA interstrand crosslinks (ICLs) (3) and involved in repair of double strand breaks (4). Mutations in the corresponding XPF gene cause specific forms of xeroderma pigmentosum, Cockayne syndrome, and Fanconi anemia, while altered XPF protein levels may be associated with disease progression and response to treatment in specific human cancers (5,6).
