Product Name
Human, Cynomolgus VEGF165 HEK293 Overexpression Lysate
Synonyms
Human MVCD1 Overexpression Lysate; Human VEGF Overexpression Lysate; Human VEGF165 Overexpression Lysate; Human VPF Overexpression Lysate
Molecule Mass
The recombinant human VEGF165 consists of 165 amino acids and predicts a molecular mass of 19.2 KDa. It migrates as an approximately 20 and 22 KDa band in SDS-PAGE under reducing conditions due to different glycosylation.
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.
Product Description
This Human VEGF-A overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of VEGF-A protein (Cat: 11066-HNAH) from the overexpression lysate was verified.
Expression Host
HEK293 Cells
Sequence Information
A DNA sequence encoding the human VEGF165 isoform (P15692-4) (Met1-Arg191) was expressed. Human and Cynomolgus VEGF165 sequences are identical.
Preparation Method
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.
Lysis Buffer
Modified RIPA Lysis Buffer: 50 mM Tris-HCl pH 7.4, 150 mM NaCl, 1mM EDTA, 1% Triton X-100, 0.1% SDS, 1% Sodium deoxycholate, 1mM PMSF.
Recommend Usage
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.
Sample Buffer
1 X Sample Buffer (1 X modified RIPA buffer+1 X SDS loading buffer).
Application
Western Blot (WB)Optimal dilutions/concentrations should be determined by the end user.
