    Author(s): Elghar Soltani, Mohammad Ahangarzadeh Rezaee and Pourya Gholizadeh*

    This survey aimed to assess the roles of pipette tip’s contamination and usage of one second-hand tip in the loading of all samples in the electrophoresis procedure, and use of second-hand tubes in PCR procedure. Three genes with different band sizes were amplified with the PCR method. Three dilutions of 1x, 0.5x and 0.1x were made for all three PCR products. After loading of each PCR products in its first well, pipette tip has not replaced and washed in 5 μl distilled water. Then, 5 μl of the washed water was loaded in the second well. Two kinds of staining methods were done, including safe stains and Ethidium- Bromide. At the same time, Non-sterile and second-hand vials were washed with 6% NaOCl and used for PCR method, again. Results showed that among all three dilutions (1x, 0.5x and 0.1x), only 1x dilutions had bands in first wells for each gene. In addition, none of .. Read More»
