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.

CBS (D8F2P) Rabbit mAb recognizes endogenous levels of total CBS protein.Species Reactivity:
Human, Mouse, Rat
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Leu220 of human CBS protein.
Cystathionine beta-synthase (CBS) is a key enzyme involved in sulfur amino acid metabolism because it catalyzes the formation of cystathionine from serine and homocysteine (1,2). The CBS protein contains a heme-binding domain that modulates enzyme activity by sensing redox changes or carbon monoxide binding (1). S-adenosylmethionine binds the carboxyl-terminal CBS domain to allosterically regulate CBS catalytic activity (3,4). In addition to catalyzing cystathionine formation, CBS also catalyzes the generation of hydrogen sulfide, a neuromodulator in the brain, through alternative reactions (5,6). Mutations in the corresponding CBS gene result in homocystinuria, an autosomal recessive disorder characterized by abnormal sulfur metabolism, mental retardation, eye anomalies, and vascular disease (7).
