Dear biochemists,
     I'm an overworked, underpayed, third-year high school science teacher at a
dirt-poor, rural school.  I have some leftover amylase and invertase that I
would like my students to use up this year.  WOULD SOMEONE RECOMMEND A
BUFFER(S) THAT COULD BE USED TO DILUTE THESE ENZYMES FOR SIMPLE ENZYMATIC
STUDIES?
                            		Thanks,
                                        Roy Clevenstine
