Hi just wondering if anyone had some ideas for this 

Q/  You want to prepare a quantity of a protein from a biological sample.  The protein has a MW of about 45kD and a pI of 6.  It binds to the amino acid tyrosine but in the crude biological sample the protein is already saturdated with tyrosine, and the protein is unstable below its isoeletric point.  Outline a scheme, by which the protein could be purified by chromatographic means..including stationary phase, and conditions for elcution etc
