Product Description
Background
In undifferentiated mouse embryonic neural precursors, sDMA histone H4R3 is prevalent, but in later stages of development, both sDMA and aDMA di-methyl H4R3 modifications are detected in post-mitotic neurons and developing oligodendrocytes. This implies that sDMA modifications may be negative epigenetic regulatory events while aDMA modifications may signal epigenetic activation sites (7).
