Terminology Problem

Post by nerdakias » Sun May 20, 2007 7:53 am

Can someone explain the terms A/J mice and puriss p.A (the complete phrase is: ''Chemicals and solvents were either puriss p.A. or purified by
standard techniques.'') ?

Thnx in advance. :D

A/J is an inborn mouse strain designation, like Balb/c or AKR/J. There are usually historical reasons for the names--like someone's initials or it's short for some particular phenotype and so on. According to Charles River Labs, A/J stands for "Aged Just In Time." Your guess is as good as mine as to what "Aged Just In Time" means.

The "puriss p.a. A" is a grade of purity (latin purus: pure, free from) I think this would be the highest analytical grade material.
