Quantitative expression of representative GACA/GATA-tagged transcripts demonstrating variations among somatic/gonadal tissues and spermatozoa. Four types of expressional profiles were uncovered with GACA; some transcripts with highest expression in testis and spermatozoa e.g. Ankyrin repeat domain (a), few in testis only e.g. Ubap1 (b), few in spermatozoa only e.g. novel pJSC3 (c), and others distributed almost uniformly in all the tissues e.g. HBGF-1 (d). Three types of expressional profiles were observed for GATA-tagged transcripts; some showed highest expression both in testis and spermatozoa e.g. novel pJSC34 (e), few in testis only e.g. novel pJSC33 (f), few others in spermatozoa only e.g. novel pJSC32 (g), and others highest in testis and spermatozoa but with minimal variation in comparison to somatic tissues e.g. novel pJSC31 (h).
