Proteins are the essential components of the tissues that play a key role in the body. Its expression in the cell or tissue under a specified set of conditions and at a particular time regulates the different body conditions either as a normal body function or as a disease state. Protein is an important building block of muscles, skin, cartilage, bones and blood. Bradford assay is a reliable advanced and cost-effective protein estimation test for determining the exact concentration of protein in different tissues of the animal. In this study, we have taken a rat suffering from protein deficiency disorder and total protein concentration in the heart, brain, liver, blood and kidney was determined. It was found that the total protein concentration in different tissues of rat i.e., heart, brain, liver, plasma and kidney was found to be 8.39 ± 0.75, 10.46 ± 0.76, 6.74 ± 0.39, 8.12 ± 0.32 mg/g of tissue and 61.27 ± 0.95 mg/mL of plasma respectively (mean ± SEM). As compared to earlier published reports the total protein concentration in different tissues like hear, brain, liver and kidney found much lower to standard value as reported by Beyer, the reason behind obtaining this kind of results may be due to the presence of insufficient amount of the protein content in different tissue of animal as suffering from protein degeneration disorder. The rat was unable to digest and store the protein or catabolism was much faster than
