Anti-H3-S10-ADP-ribose antibody, clone AbD33644, recognizes Histone H3, ADP-ribosylated at Serine 10. This antibody also recognizes the less abundant H3 site H3-S28-ADP-ribose, however this is with a lower affinity and is due to the similarities between sequences flanking the two H3 target sites. This clone does not detect poly-ADP-ribose in a site-specific manner (Bonfiglio et al. 2020).

Poly(ADP-ribose) polymerase 1 (PARP1) is an early responder to DNA damage in human cells. Upon binding to genomic lesions PARP1 is able to transfer a mono- or poly-ADP-ribose residue from nicotinamide adenine dinucleotide (NAD+) to their substrate proteins, for chromatin decompaction and repair factor recruitment (Bütepage et al. 2015, Suskiewicz et al. 2020).

During the DNA damage response, serine is the primary target for PARP1 ADP-ribosylation which uses Histone PARylation factor 1 (HPF1) as an accessory factor to switch the amino-acid specificity of PARP1 from aspartate/glutamate to serine residues (Bonfiglio et al. 2017, Suskiewicz et al. 2020). During the DNA damage response PARP1 and HPF1 primarily target PARP1 itself and histone H3, ribosylating these targets.

This anti-H3-S10-ADP-ribose antibody, clone AbD33644 is tagged with a SpyTag2 at the C-terminus of the Fab heavy chain, enabling the user to couple it to a SpyCatcher reagent for conversion to alternative formats in less than an hour. It has the same specificity than the bivalent human recombinant Fab antibody HCA357, clone AbD33644.

This product is shipped at ambient temperature. It is recommended to aliquot and store at -20°C on receipt. When thawed, aliquot the sample as needed. Keep aliquots at 2-8°C for short term use (up to 4 weeks) and store the remaining aliquots at -20°C.

Avoid repeated freezing and thawing as this may denature the antibody. Storage in frost-free freezers is not recommended. Should this product contain a precipitate we recommend microcentrifugation before use.
