Different properties of a biomolecule can be employ for the breakup. Proteins are usually a classify(p) use chromatographic techniques. In this experiment we used gel filtration chromatography – method acting based detachment of molecules according to their size. Using this technique, BSA (Bovine Serum Albumin ) was separated from a solution containing it. Two different spectroscopic assays were carried let on: the Bradford Assay and protein stopping point by absorbance measurement at 280 nm. These enabled us to identify and mensurate the BSA containing samples gained using gel chromatography separation technique (Illenberger et al., 2008).

Materials and Methods The experiments were carried out as described in the manual of arms with the following exceptions: in the photometrical analysis of gel fractions at 280 nm both samples were weaken twice to obtain good absorption values smaller than 1 for higher accuracy . When measuring stick BSA absorbencies for! the calibration curve, all standards were lively twice, not once, therefore a mean value of cardinal different samples was used for obtaining separately point of the calibration curve. For formulation of calibration standards 10 mg/mL BSA stock solution was used. 2 Experiment 1-7.
