The homogenate was then extracted twice using similar method above and protein concentration in the supernatant was measured by Lowry method (Ohnishi and Barra, 1978).
Estimation of laccase was performed using Lowry method 9 to determine the concentration difference of laccase obtained from Trametes versicolor and Bacillus subtilis 1133.
In the preparations obtained and eluates of fractions the content of proteins was controlled by Lowry method (Lowry, Rosenbrough, Farr, Randai, 1951) after dialysis at all stages.
Protein content estimation of each conjugate was done by Lowry method. (15,16)
The protein content of the aqueous extract of seeds (AS) and its fractions (F25, F50 and F75) was determined by the Lowry method, using bovine serum albumin (BSA) as reference.
P-1 shows 1.24 mg/100 g plants but computer software computed the colour protein by Lowry method and 1.68 mg/100 g by intensities of stained plant sections and the colour Bradford method respectively.

Stock solutions contained 6.39 g/L S-100A1, 1.3 g/L S-100B (as determined using the Lowry method), and 1 g/L S-100A1-A1, S-100A1-B, and S-100B-B (as specified by the manufacturer).
The Lowry method is complicated to perform and has low sensitivity.
Total protein content of plasma sample was measured by modified Lowry method (Lowry et al., 1951) or by determining absorbance of protein solution at 280 nm (based on the fact that 1 mg per ml sample of albumin gives an absorbance of 1.0 at 280 nm).
