Re: "fringe" extinction coefficient

Bo,
4.1 fringes per 1 mg/ml of protein.  Proteins will not exhibit
any variations as long as there is not a lot of carbohydrate bound to
it.  Reference:  Babul & Sftellwagen 1969 Anal. Biochem 28 216-221.

Will be talking to you more about printers and Linux next week.
