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.

MEIS1/2 Antibody recognizes transfected levels of total MEIS1 and MEIS2 proteins.Species Reactivity:
HumanSpecies predicted to react based on 100% sequence homology:
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human MEIS1 protein. Antibodies are purified by protein A and peptide affinity chromatography.
Hox, Pbx, and Meis are families of transcription factors that bind DNA via their homeodomains. Members from each family form heterodimers to give rise to complexes with unique DNA binding specificities. Homeodomain containing proteins are frequently involved in normal developmental processes, but can also be associated with tumorigenic states (1). MEIS proteins belong to the TALE (Three Amino Acid Loop Extension) homeobox containing transcription factor family. MEIS1 has been associated with leukemogenesis and neuroblastoma (2,3) while MEIS2 is known to play an important role in the transcriptional program that is induced in normal pancreatic development (4) and cardiogenesis (5).
