Article Snippet: PfRipr5 nucleotide sequence ( ) was codon-optimized for expression in insect or human cells, with an N-terminal gp67 SP sequence to allow secretion into the culture medium, a C-terminal His 6 -tag to allow purification, and a Kozak consensus sequence (GCCACT or ACC for human or insect expression plasmid, respectively) as the translation initiation site (synthetized by GenScript, Leiden, the Netherlands).

Techniques: Concentration Assay, SDS Page, Purification, Enzyme-linked Immunosorbent Assay, Expressing, Western Blot, Staining

Optimization of PfRipr5 production using insect cells. (A) Optimization strategies devised. (B) Relative PfRipr5 concentration at the TOH between each optimization condition and the baseline production setup (infection with rBAC gp67 without culture temperature shift). A denotes alanine, G denotes glycine, and S denotes serine. Infections were performed using CCI = 2 × 10 6 cell/mL and MOI = 0.1 pfu/cell. Data are expressed as mean ± standard deviation and is relative to three biological replicates ( n = 3).

Production of the PfRipr5 recombinant protein. (A) Kinetics of cell growth and viability upon infection of insect High Five (green) and Sf 9 (orange) cells at different combinations of cell concentration at infection (CCI) and multiplicity of infection (MOI). (B) Kinetics of cell growth and viability upon transfection of human HEK293 cells at different combinations of the PfRipr5 plasSmid DNA (pDNA) concentration (pDNA) and ratio pDNA:PEI. (C) Relative PfRipr5 concentration at the time-of-harvest (TOH) of each production condition. Data are expressed as mean ± standard deviation. For insect cells, data are relative to three biological replicates ( n = 3). For human cells, data are relative to one biological replicate ( n = 1). For figure (A,B) , VCC denotes viable cell concentration. For figure (C) , relative PfRipr5 expression was assessed by a densitometry analysis of western blot as described in the M&M section; graph is normalized at 1 for the best condition using human cells [i.e., (pDNA) = 0.5 mg/L and ratio pDNA:PEI = 1:2 (w:w)].
