About the inventions

Essence of the invention:

  • Simple (from the chemist's point of view) low molecular peptide derivatives forming aqueous gels in smaller concentrations than gelatine and starch are described in the patent of Latvia and the patent of USA Nr. 5955434.
  • Peptide aqueous gels are used as pseudo-high molecular carriers in immunology for the production of antibodies against so-called small molecules that do not contain chemical functional groups and for the resolution of dyes in chromatography. Unlike real high molecular carriers gels can be melted down in organic resolvent after chromatography accordingly avoiding the non-specific absorbing.
