Purification and characterization of riboflavin carrier protein from egg white of South Indian spotted owlet (athene brama).

ABSTRACT

Riboflavin carrier protein has been isolated and purified from the Indian spotted owlet. The protein was purified to its homogeneity. Purification was achieved successfully by DEAE_ Sepharose column chromatography and gel filtration chromatography on Sephadex G-100. The protein content was estimated with Lowry method. The purity of the proteins was judged by SDS-PAGE technique. The molecular weight of the protein was found to be 29 Kd. The protein was characterized using absorption, fluorescence and CD spectral analysis. Significance of the above results are discussed in the present communication.
