Abstract

Background and purpose: LACTOFERRIN is a multifunctional protein, which is useful for clinical and commercial applications. Recently it has been shown that ingestion of LACTOFERRIN has advantages including: immune system modulation, anti-microbial activity and antioxidant in neonates and adults in both animals and humans. The present study has been conducted with the purpose of ISOLATION and optimal PURIFICATION of LACTOFERRIN from cow’s milk.Materials and methods: Bovine colostrum was collected during 72 hours of delivery. First, milk fat was separated. To Isolate LACTOFERRIN from the rest of the milk proteins, the ISOLATION process was conducted in two steps. Casein was precipitated using ammonium sulfate and in the next step LACTOFERRIN was isolated using CM-Sephadex-C50 CATION EXCHANGE CHROMATOGRAPHY column with FPLC. To identify the isolated protein SDS-PAGE method was used.Results: The pure active protein, with a molecular weight of 80 kDa, with concentration of 2.4 mg/ml was obtained. The degree of PURIFICATION implementing after CATION EXCHANGE CHROMATOGRAPHY column was 4 and PURIFICATION efficiency 90%.Conclusion: Considering the increase in the clinical and nutritional applications of LACTOFERRIN and particularly its immunomodulatory effects, finding an appropriate and efficient PURIFICATION method is very important. The results of the study show that the above-mentioned method, apart from simplicity and speed, can result in ISOLATION of highly pure LACTOFERRIN.
