Fig. 1. Northern analysis of galectin 1 transcripts in postnatal mouse testis. RNA samples from P7, P14, P28 and P56 testes, P56 epididymis and P56 XXSxra testes all contain galectin 1 transcripts migrating as a cluster of bands at approximately 0.6 kb. A discrete band of slower migrating galectin 1 transcripts (arrowhead) is present only in the P28 and P56 testis RNA. Each track contains 10 µg of total RNA.
