RE: ks values

Hi David,
	
	You might do better with the form  1/s = (1 +Ksc)/s0; it's linear 
over a wider range.

You should check the papers by Arthur Rowe on this subject.

Subject: ks values

OK RASMB'ers,
 Probably a silly question, but I'm going to ask it anyway....

 I've been doing a service run for someone, starting with sed. vel over 9 concentrations.
>From this I see a nice linear decrease with concentration for which I can fit the relationship s=s0(1-ks*c).
For a globular protein (which I'm assuming it is) what is a 'typical' value of ks. 

I get 0.18 (ml/mg). 

I haven't got round to fitting a more elegant model as yet, but will once I've waded through the literature.

Thanks in Advance....

Dave Scott.
