Human PARP3 Baculovirus-Insect cells Overexpression Lysate: 产品信息
This Human PARP3 overexpression lysate was created in Baculovirus-Insect cells and intented for use as a Western blot (WB) positive control. Purification of PARP3 protein (Cat: 11190-H20B) from the overexpression lysate was verified.
A DNA sequence encoding the C-terminal segment of human PARP3 isoform 1 (Q9Y6F1-1) (Met 1-Leu 533) was fused with the N-terminal polyhistidine-tagged GST tag at the N-terminus.
The recombinant human PARP3/GST chimera consists of 768 amino acids and has a calculated molecular mass of 87.8 kDa. It migrates as an approximately 95 kDa band in SDS-PAGE under reducing conditions.
Human PARP3 Baculovirus-Insect cells Overexpression Lysate: 使用指南
Cell lysate was prepared by homogenization of the over-expressed cells in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors (Sigma). Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (Bio-Rad protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50 mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
1. Centrifuge the tube for a few seconds and ensure the pellet at the bottom of the tube.
2. Re-dissolve the pellet using 200μL pure water and boil for 2-5 min.
1 X Sample Buffer (1 X modified RIPA buffer+1 X SDS loading buffer).
稳定性 & 储存条件
Store at 4℃ for up to twelve months from date of receipt. After re-dissolution, aliquot and store at -80℃ for up to twelve months. Avoid repeated freeze-thaw cycles.
Western Blot (WB) Optimal dilutions/concentrations should be determined by the end user.

Poly(ADP-ribose) polymerase 3 (PARP3) is an important member of the PARP family and shares high structural similarities with both PARP1 and PARP2. Poly(ADP-ribose) polymerase 3 (PARP3), a critical player in cellular response to DNA double-strand breaks (DSBs), plays an essential role in the maintenance of genome integrity. The ADP ribosyl transferase [poly(ADP-ribose) polymerase] ARTD3(PARP3) is a newly characterized member of the ARTD(PARP) family that catalyzes the reaction of ADP ribosylation, a key posttranslational modification of proteins involved in different signaling pathways from DNA damage to energy metabolism and organismal memory.
