  • Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

  • TCR Screening Services

  • Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

Specificity and Use

MYB / c-Myb antibody was raised against 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.
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.
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 kD in size corresponding to phosphorylated c-Myb by western blotting in the appropriate cell lysate or extract.

MYB / c-Myb is a transcription factor that is a member of the MYB family of transcription factor genes. The protein contains three domains, an N-terminal DNA-binding domain, a central transcriptional activation domain and a C-terminal domain involved in transcriptional repression. This protein plays an essential role in the regulation of hematopoiesis and may play a role in tumorigenesis. Alternative splicing results in multiple transcript variants.

Western blot

Western blot
Western blot of Rabbit c-Myb pT486 antibody. Lane 1: Cos7 cells were either null for c-Myb. Lane 2: Cos7 cell lysates transfected with c-myb, no treatment. Lane 3: Cos7 cell lysates transfected with c-Myb and treated with okadaic acid to include phosphorylation of c-Myb. Load: 35 ug per lane. Primary antibody: The left blot was probed with anti-c-Myb antibody, the right blot was probed with anti-c-Myb pT486 antibody at 1:2500 for overnight at 4C. Secondary antibody: IRDye800 rabbit secondary antibody at 1:10000 for 45 min at RT. Block: PBS-Tween (0.05%) overnight at 4C. Predicted/Observed size: 75, 98, and 125kDa corresponding to overexpressed c-Myb (arrow): wild-type, with one attached SUMO molecule, and with two attached SUMO molecules, respectively.
