'THT reference

Making a reference of pure chaplins is of great importance when comparing results. For a reference 22 mg of extracted and freeze-dried celwalls of streptomyces were used. Chaplins from these cellwalls were then purified by TFA treatment. The monomerized chaplins were diluted in 1 ml demiwater. Then a variety of dilutions was made with demiwater.

Analasys was done by THT and SDS page.

Modellers: More literature research on ComXPA. Joël, Laura. Researching parts registry for information which is required to build an information standard Arend
