    Protocol

    Specificity / Sensitivity

    Histone H3 (K27M Mutant Specific) (D3B5T) Rabbit mAb recognizes endogenous levels of K27M mutant histone H3.1, H3.2, and H3.3 proteins. The antibody may cross-react with wild-type histone H3.1, 3.2, and 3.3 when used at a high concentration. Careful titration of this antibody may be required to obtain optimal specificity.

    Species Reactivity:

    Human, Mouse

    The antigen sequence used to produce this antibody shares 100% sequence homology with the species listed here, but reactivity has not been tested or confirmed to work by CST. Use of this product with these species is not covered under our Product Performance Guarantee.

    Species predicted to react based on 100% sequence homology:

    Rat, Xenopus, Pig

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to K27M mutant sequence of human histone H3.3 protein.

    Background

    Diffuse intrinsic pontine glioma (DIPG) is an aggressive brainstem astrocyte tumor arising mostly in children, leading to a long-term survival rate of less than 10%. Multiple whole-genome sequencing studies of DIPG patients identified commonly occurring mutations in the H3F3A gene encoding histone H3.3. One of these mutations, a lysine to methionine amino acid substitution (K27M), is found in up to 78% of DIPGs and 22% of non-brainstem pediatric gliomas (1-3). This mutation is associated with poor prognosis, with a mean survival time of 0.73 years for patients with the K27M mutation versus 4.6 years for patients without the mutation (1-3). Expression of the K27M mutant histone H3 is accompanied by a dramatic reduction in the levels of polycomb repressive complex 2 (PRC2)-mediated trimethylation of histone H3, changes in the distribution of PRC2 on the genome, and altered expression of genes associated with various cancer pathways (4-6).
