Recombinant Arabidopsis thaliana MBP-PARP2protein (AT2G31320)
For reconstitution add 50 µl of sterile water.
Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes.
No confirmed exceptions from predicted reactivity known in the moment
100 µg of total protein from 14 days old Arabidopsis thaliana seedlings extracted with extraction buffer (2% SDS, 50 mM Tris-HCl, pH 8.0, protease inhibitor cocktail (Sigma, P9599) 1:100) and denatured with Laemmli sample loading buffer at 70°C for 10 min were separated on 10 % SDS-PAGE and blotted 2h to PVDF using tank transfer. Blots were blocked with 5% milk for 1h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 1 000 in 1% milkTBS-T overnight with agitation at 4°C. The antibody solution was decanted and the blot was rinsed briefly twice, then washed once for 15 min and 3 times for 5 min in TBS-T at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated) diluted to 1:10 000 in 1% milk TBS-T for 1h at RT with agitation. The blot was washed as above and developed for 5 min with chemiluminescent detection reagent. Exposure time was 2-5 min.

PARP (EC=22.214.171.124) is a protein involved in the base excision repair pathway (BER) and is catalyzing the poly(ADP-ribosyl)ation of a limited number of acceptor proteins involved in chromatin architecture and in DNA metabolism. PARP is a marker of a single-strand breaks (SSBs), Rybaczek and Kowalewicz-Kulbat (2013).
Alternative names: ADPRT 2, NAD(+) ADP-ribosyltransferase 2, Poly[ADP-ribose] synthetase 2.
