[bionet.molbio.proteins] help needed on proteases............

BS04@primeb.dundee.ac.uk (03/15/91)

Networkers,

  Could I have some advice on Protease inhibitors? I am just about to start
using them as part of my extraction buffer. The amounts I need to buy are
quite small and for every extraction even less.

 The  question I would like to ask is: Is it possible to make up the
solution in the vial the chemical comes in and freeze aliquots? Often when
only small amounts of a chemical are obtained a fraction always seems to be
left in the lid/sides/bottom of the vial! and quite alot is "lost".

   The chemicals I intend to use are (1) Aprotinin (2) Leupeptin (3) Pepstatin
If anyone has any alternatives/recommendations on the use of these chemicals
I would be more than grateful.

 Yours


   Andrew Johnston.
