  • Patent number: 10047134
    Abstract: The present disclosure relates to a comprehensive model for expression of recombinant peptides by Pichia pastoris. The model uses an easily controllable variable called ‘critical nutrient ratio’ for obtaining a right balance between product synthesis and it's degradation during the fermentation process. The extra cellular concentration of precursor could be increased by about 10 folds and the degradation constants could be reduced by about 10-20 folds for intracellular and extracellular cases respectively by controlling critical nutrient ratio and addition of soya flour hydrolysate and EDTA.

  • Patent number: 9638696
    Abstract: The present disclosure relates to a process for detecting and optionally quantifying an analyte in a sample in the presence of a soluble target of the analyte. The soluble target forms a complex with the analyte and thus may interfere in determining the total analyte concentration. The process of the present invention utilizes a unique modified citrate buffer for diluting the sample containing the analyte and the soluble target which in turn helps in dissociating the analyte-soluble target complex, thereby enabling the process of the disclosure to detect and optionally quantify measure the analyte accurately.
