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.

LACTB Antibody recognizes endogenous levels of total LACTB protein.Species Reactivity:
Human, Mouse, Rat, Monkey
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human LACTB protein. Antibodies are purified by protein A and peptide affinity chromatography.
LACTB is a serine beta-lactamase-like protein that is most prominently expressed in skeletal muscle, heart and liver (1). It contains an amino-terminal transmembrane domain and is localized to the mitochondrial intermembrane space, where it is polymerized into stable filaments that promote intramitochondrial membrane organization and micro-compartmentalization (2). Studies in multiple breast cancer cell types have shown that LACTB can function as a tumor suppressor by promoting decreased levels of phosphatidylserine decarboxylase (PISD), leading to reduced cell proliferation (3). In accordance with this, levels of LACTB have been shown to be downregulated in hepatocellular carcinoma and colorectal cancer and associated with poor prognosis in both (4,5).
