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.

Caspase-14 (D3J3D) Rabbit mAb recognizes endogenous levels of total caspase-14 protein. Endogenous levels of the p20 activated subunit have not been detected.Species Reactivity:
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala71 of human caspase-14 protein.
Caspases are a family of cysteine proteases that play an essential role in carrying out apoptosis. Caspase-14, also named MICE, is a unique member of the caspase family with restricted expression; it is found in embryonic tissues and adult skin (1,2). Caspase-14 is weakly processed into p18 and p11 subunits by caspase-8 (2). Caspase-14 may not play a role in apoptosis (2), but instead may regulate keratinocyte differentiation (3). Expression of caspase-14 may protect from psoriasis (4,5) and irradiation damage (6). Caspase-14 may also be responsible for proteolytic processing of filaggrin during terminal differentiation of keratinocytes (6).
