This Human ERP72 overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of ERP72 protein (Cat: 13333-H02H) from the overexpression lysate was verified.
A DNA sequence encoding the human PDIA4 (P13667) (Met1-Thr641) was expressed, fused with the Fc region of human IgG1 at the C-terminus.
The recombinant human PDIA4/Fc is a disulfide-linked homodimer. The reduced monomer comprises 862 amino acids and has a predicted molecular mass of 97.2 kDa. The apparent molecular mass of the protein is approximately 96 kDa in SDS-PAGE under reducing conditions
Human ERP72 HEK293 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.

ERP72, also known as PDIA4, is an endoplasmic reticulum luminal protein which belongs to the protein disulfide isomerase family. ERP72 is a stress protein and participates in the catalysis of protein-S-S-bond rearrangement. Both PDIA4 and PDIA3 function as proteases, protein disulfide isomerases, phospholipases or an arrangement of these. ERP72 compose part of a large chaperone multiprotein complex comprising CABP1, DNAJB11, HSP90B1, HSPA5, HYOU, PDIA2, PDIA4, PPIB, SDF2L1, UGT1A1 and very small amounts of ERP29, but not, or at very low levels, CALR nor CANX.
