Fig. 7. Tissue specificity of genes expressed in the salivary glands of adult female Anopheles gambiae mosquitoes as evidenced by RT–PCR analysis. Total RNA from female salivary glands (sg), carcasses (c; adult females with salivary glands removed) or adult males (m) was amplified using the gene-specific primers indicated on the right. Amplifications are grouped according to pattern of expression: (A) housekeeping; (B) female gland specific; (C) enriched in female glands; (D) female glands and adult males; (E) rpS7, ribosomal protein S7 used for normalization.
