This CV Coxsackievirus A16 VP4 overexpression lysate was created in Baculovirus-Insect Cells and intented for use as a Western blot (WB) positive control. Purification of Coxsackievirus A16 VP4 protein (Cat: 40535-V31B) from the overexpression lysate was verified.
A DNA sequence encoding the VP4 of Coxsackievirus A16 (Cox A16) (strain G-10) (AAA50478.1) (Gly2-Lys69) was expressed with the Fc region of rabbit IgG at the C-terminus.
The recombinant VP4 of Coxsackievirus A16 (Cox A16) (strain G-10) consists of 292 amino acids and predicts a molecular mass of 32.6 kDa.
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.
