Simple
picrate paper kit for determination of the cyanogenic potential of cassava flour.
Urea (urease method), creatinine (alkaline
picrate method), bilirubin (Mod.
Twenty monogeneans were prepared as whole mounts using ammonium
picrate glycerine (APG) according to the method of (Malberg, 1970).
Colorimetric determination of trimethylamine as the
picrate salt.
An overnight fasting blood sample was taken in the morning, and the serum creatinine was analyzed using a HITACHI 7150 (before 2005) or a TOSHIBA C8000 (after 2005) analyzer with the uncompensated Jaffe method involving an alkaline
picrate kinetic test (Myers et al.
The EuBIVAS project: within-and between-subject biological variation data for serum creatinine using enzymatic and alkaline
picrate methods and implications for monitoring.
All these possible interferences can potentially interfere with alkaline
picrate to give false increase in serum creatinine (4).
In the sample, creatinine reacts with
picrate in alkaline medium, forming a colored complex.
Cyanides were evaluated in the cassava roots and in the different gari sample using
picrate colorimetric method proposed by de B.
Serum and urine creatinine were measured using a Jaffe alkaline
picrate method (Beckman-Coulter).
Serum urea was estimated by Berthelot's method[5] while creatinine was estimated by alkaline Jaffe's
Picrate method.[6] These biochemical parameters were determined by using a fully automated clinical chemistry analyzer.
