Quantitative Measurement of Anti VSVG Epitope Peptide Binding

Chip Design

  • Epitope (known) YTDIEMNRLGK
  • HA, c-myc, VSVG, and flag epitope and other peptide sequences (see figure 3 below for detail)
  • >3 redundancy
  • CV < 30%

Assay

  • Antibody: anti-VSVG(1 ng/ml)
  • 200 µl TBS
  • Temp: 4oC
  • Reaction time: 1 hour

Detection

  • Cy5-IgG (100ng/ml)

Results
