C-MYB PT486 Antibody Description

This antibody is designed, produced, and validated as part of a collaboration between Rockland and the National Cancer Institute (NCI) and is suitable for Cancer, Immunology and Nuclear Signaling research. The transcription factor c-Myb plays an important role in the development of all hematopoietic lineages during definitive hematopoiesis. Its critical role in hematopoiesis has been first demonstrated in experiments with targeted disruption of the c-Myb gene where deletion of both alleles of the c-Myb gene was embryonally lethal due to severe anemia. c-Myb is a short-lived sequence specific DNA-binding protein that regulates transcription of several important genes involved directly in cellular processes such as proliferation, differentiation, and apoptosis. Post-translational modifications such as phosphorylation, acetylation, ubiquitination, and conjugation of SUMO proteins are crucial for modulation of the transactivation activity of c-Myb.
This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to an internal region of mouse c-Myb protein surrounding amino acid residue 486.

Storage Condition
Store vial at -20° C or below prior to opening. This vial contains a relatively low volume of reagent (25 µL). To minimize loss of volume dilute 1:10 by adding 225 µL of the buffer stated above directly to the vial. Recap, mix thoroughly and briefly centrifuge to collect the volume at the bottom of the vial. Use this intermediate dilution when calculating final dilutions as recommended below. Store the vial at -20°C or below after dilution. Avoid cycles of freezing and thawing.
Application Note
This affinity purified antibody has been tested for use in ELISA and western blotting using M1 cells which express endogenous wild-type c-Myb protein and in COS7 cells transfected with c-Myb.  Specific conditions for reactivity and detection of phosphorylated c-Myb should be optimized by the end user.  Expect a band approximately ~75 kDa in size corresponding to phosphorylated c-Myb by western blotting in the appropriate cell lysate or extract.
This affinity-purified antibody is directed against the phosphorylated form of mouse c-Myb protein at the pT486 residue. Antiserum was first purified against the phosphorylated form of the immunizing peptide.  The resultant affinity purified antibody was then cross adsorbed against the non-phosphorylated form of the immunizing peptide.  Reactivity occurs against mouse c-Myb pT486 protein and the antibody is specific for the phosphorylated form of the protein.  This antibody reacts with endogenous c-Myb protein and also SUMOylated overexpressed c-Myb protein in transfected Cos7 cells. Reactivity with non- phosphorylated mouse c-Myb is minimal by ELISA and western blot. A BLAST analysis was used to suggest reactivity with c-Myb from mouse based on a 100% homology with the immunizing sequence.  Expect reactivity with c-Myb from rat, pig, human, horse, platypus, opossum, orangutan, spider monkey, bonobo, gorilla, and chimpanzee; with a v-myb myeloblastosis viral oncogene homolog, all isoforms (also avian version) from human; and with a protooncogene c-myb, and a v-myb myeloblastosis viral oncogene homolog (avian), both from cattle, all based on a 93% homology with the immunizing sequence.  Cross-reactivity with c-Myb from other sources has not been determined.
