[Biochemical genetic marker of mouse salivary protein in mouse]

It has been reported by BALAKRSHANN and ASHTON that about 20-30 bands of human salivary protein separated by polyacrylamide gel electrophoresis (PH 8.0) were detected by staining with Coomassie brilliant blue R. Employing the same method, MATSUSHIMA discovered five main regions (I-V) in mouse salivary protein (Msp) separated by poly-acrylamide gel electrophoresis (PH 8.0). He also discovered distinctive features of biochemical genetic markers among each of the five regions. In this experimental study, we investigated biochemical genetic markers of Msp of C3H/HeJ, BALB/c, BALB/k and NOD/shi strains. The following were the results of the present study. 1) The results of C3H/HeJ and BALB/c mice were in accord with those of MATSUSHIMA's. 2) The BALB/k mouse showed the same results as the BALB/c the difference in sex of Msp-1 seemed to have no relation to H-2 complex. 3) With the NOD/she strain, Msp-3 showed the b-type, Msp-2 the a-type, Msp-1 the o-type showed no difference based on sex, that is to say, F-type in both male and female. Amylase-1 showed the b-type.
