BandAid Application

Experiments

Aim: To check if it is feasible for the peptides to pass through the selected membranes (Cellulose Nitrate Membrane and PTFE Membrane).

Procedure:
  1. Dissolve the peptides. Signiferin was dissolved in water, in order to dissolve maximim 1M of NH4HCO3 was added in order to gain an end concentration of 5mM.
  2. The peptide solutions were measured, using the nanodrop, and we determined the initial absorbance. Using absorbance A= εcL=εc when L = 1cm [1] the concentration was measured
  3. In order to make diffusion measurable, we folded the membrane like a filter paper and placed it in the peptide solution
