Constants

Here is the link to the latest contants (for the Windows & DOS Maxc programs) which contain two files of constants in two formats:

Standard Set [most common chelators and metals] in TCM and CCM formats Extended Set [additional metals often asked for] in TCM and CCM formats

I am labeling the constants files starting with CMC for chelator-metal-constants and then the next 4 characters will say the month and year of release. Finally an "S" or "E" for which set. So the above mentioned constants will be CMC1002S.TCM, CMC1002S.CCM, CMC1002E.TCM and CMC1002E.CCM

ALL CONSTANTS ARE TAKEN FROM THE MOST RECENT VERSION OF THE NIST DATABASE AND THEN CORRECTED, IF POSSIBLE, TO FIT THE MAXC FORMAT

You can get a preview of the constants in a large table here.

If you want specific metals and chelators in a file of constants and do not want to try and figure this out yourself, I will try and find the constants and construct the file for you. Not all combinations are possible. A request for Cu1 came in recently, but there are no constants for Cu1 in the NIST database that I could find.

SOURCES OF CONSTANTS

Check out: http://www.nist.gov/ts/msd/srd/nist46.cfm

NIST Critical Stability Constants. Covers most of the constants in Martell & Smith.

The program and database are no longer maintained. You can download for free. It runs in Windows 95-XP and in Vista/W7 in Windows XP virtual mode. The database is NOT compatible with 64 bit operating systems. I use it in XP virtual mode on Windows 7 64 bit myself.

It complements, but does not replace the Martell & Smith "Critical Stability Constants" volumes.

Invitrogen has information for its fluorescent probes at: http://probes.invitrogen.com/handbook/sections/1900.html

I did some work on getting these into MAXC format.

Magnesium indicators and their constants are on this page.
