Human ENTPD3 Baculovirus-Insect cells Overexpression Lysate: Product Information
This Human ENTPD3 overexpression lysate was created in Baculovirus-Insect cells and intented for use as a Western blot (WB) positive control. Purification of ENTPD3 protein (Cat: 10909-H08B) from the overexpression lysate was verified.
A DNA sequence encoding the human ENTPD3 (O75355) extracellular domain (Gln 44-Pro 485) was fused with a polyhistidine tag at the C-terminus and a signal peptide at the N-terminus.
The recombinant human ENTPD3 (aa44-485) consists of 452 amino acids and predicts a molecular mass of 51 kDa. It migrates as an approximately 50 KDa band in SDS-PAGE under reducing conditions.
Human ENTPD3 Baculovirus-Insect cells Overexpression Lysate: Usage Guide
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).
Stability & Storage
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.
