DETERMINATION OF GLYCOGEN IN BEE ORGAN TISSUES AS AN ENERGY METABOLISM PARAMETER by I. V. Serduchenko, N. N. Gugushvili

“…Ghoreishi’s colorimetric method used today is time-, labor- and cost-consuming as the major reagent – orcin – is quite expensive. Comparison of cost-effectiveness of the two methods demonstrated that the proposed technique makes it possible to reduce expenses by using a more available and less expensive resorcin instead of orcin and reducing total test time from 4 to 3 hours 5 minutes. …”
