Comparative Study on Tryptic Peptide Mapping of Globin Beta Chains and the Genotype from Nineteen Inbred Strains of Mice / 第二军医大学学报

ABSTRACT

This study represents the first description of structural variations in the globin beta chains of 19 strains of inbred mice. The trypic pep tide mapping of beta chains of globin from BALB/c, BALB/cA, BALB/cJ, BALBcJ-nu, BALB/nu/ + ,BALB/cyJax,B10,B10A/sui,C57BL/6,C57BL/10snJ,SMMC/B,SMMC/C, C3H/He, CFW, DBA/2,SWI,Swars/nu/+,SSB and 129/sv strains of mice was established. The results showed that the position of peptide spots upon fingerprint mapping of beta chains was obviously different in comparison with each other. The different patterns of variability and polymorphism found in the various mouse species may then have come into being as a consequence of the action of selective forces on the various new beta chains which were created by some exchange processes.
