Anti-crotonyl-Histone H2A (Lys119) rabbit pAb

Cat#:PTM-505Ab Type:P

Ab Size:100 μlApplications:WB

Species:H M RPrice:¥ 3780.00


Product Description

The rabbit-derived antibody is purified with protein A-conjugated agarose followed by crotonylated histone H2A (Lys119) peptide affinity chromatography. It specifically recognizes histone H2A with crotonylation at Lys119.  

Source/Purification

This product is produced by immunizing rabbits with a synthetic crotonyl peptide corresponding to residues surrounding Lys119 of human histone H2A. Antibodies are purified by protein A-conjugated agarose followed by crotonylated histone H2A (Lys119) peptide affinity chromatography.  

Specificity

H2A

Recommended Applications

ELISA, WB; Not tested in other applications *WB=Western blotting

Recommended antibody dilution

WB: 1:2000

Important

 For Western blotting,  incubate membrane with diluted antibody in 5% nonfat milk, 1 x TBS, 0.1%  Tween-20 for two hours at room temperature with gentle shaking.  

 Use at an assay dependent concentration.  Optimal dilutions/concentrations should be determined by the end user.  

 Anti-crotonyl-Histone H2A (Lys119) rabbit pAb  

 A. Dot  blotting analysis on indicated amount of crotonylated H2A peptide at Lys119  (lane 1), crotonylated H2A peptide at Lys118 (lane2) and unmodified H2A peptide  at Lys119 (lane 3) using crotonyl-histone H2A (Lys119) rabbit pAb.


 B. Western blotting analysis on 30 μg of crude proteins  from HeLa whole cell lysates with (right) or without (left) treatment of sodium  crotonylate treatment (30 mM, 4 hours) using crotonyl-histone H2A (Lys119) rabbit  pAb (1:2000).  

 

Scientific Description

Histones are subjected to a variety of enzyme catalyzed modifications, including acetylation, methylation, phosphorylation, ubiquitylation, etc. Crotonylation of lysine is a newly identified reversible modification controlling chromosome structure and gene transcription. Lysine crotonylation is highly conserved in eukaryotic cellsfrom worm to human. The unique structure and genomic localization of histone lysine crotonylation suggest that it is mechanistically and functionally different from histone lysine acetylation. Specifically, in both human somatic and rabbit male germ cell genomes, histone crotonylation marks either active promoters or potential enhancers. Crotonylation of histone H2A at Lys119 may play a vital role in the epigenetic modulation, including chromatin remodeling and DNA transcriptional regulation.
