1/400. Use with paraformaldehyde or methanol-fixed cells.
Histone methyltransferase that specifically methylates 'Lys-4' of histone H3, when part of the SET1 histone methyltransferase (HMT) complex, but not if the neighboring 'Lys-9' residue is already methylated. H3 'Lys-4' methylation represents a specific tag for epigenetic transcriptional activation. The non-overalpping localization with SETD1B suggests that SETD1A and SETD1B make non-redundant contributions to the epigenetic control of chromatin structure and gene expression.
ChIP on chip - hSET1 antibody - ChIP Grade (ab70378)
Ab70378 (10 µg) was used to immunoprecipitate chromatin from K562 cells. Immunoprecipitated and reference DNA were amplified by ligation-mediated PCR and the products labeled with fluorescent dUTPs. The labeled ChIP and reference DNA were pooled, hybridized to a DNA microarray and analyzed. As a control a similar experiment was performed using normal rabbit IgG.
