Figure 3: Electrophoretic profile of Iranian P. papatasi salivary glands protein. It was analyzed by SDS- PAGE using 15% poly-acrylamide gel under non reducing conditions. A. Extracted protein of 40 salivary glands lead to 0.03μg/μl protein which 0.75μg was loaded in a well and stained with Coomassie brilliant blue. S: Salivary gland protein profile of P. papatasi, M: Molecular weight marker (SNAP29: Synaptosomal-associat-ed protein 29, catalog number: OAAN01135, 29kDa, Aviva Systems Biology Corporation). B. Extracted protein of 10 salivary glands lead to 50μg protein which 12.5 μg was loaded in a well stained with silver nitrate. S: Salivary gland protein profile of P. papatasi. M: Molecular weight marker (Cin-naGen corporation, catalog number: SL7001 (PR901641), 11–100 kDa). The arrows show protein bands.
