Figure 1: Gel electrophoresis of STXBP2 gene. A) Positive Control Lane: the figure shows the amplification of exons 1 to 19 of STXBP2. First line is DNA Molecular Weight Marker XIV 100 base pair (Roche). B) UPN 904 Lane: The figure shows the amplification of exons 1 to 16 and the absence of PCR product for exons 17, 18 and 19 (highlighted in red box). In the first line there is DNA Molecular Weight Marker XIV 100 base pair (Roche). C) No Template Control (NTC) Lane. The figure shows absence of amplification in NTC.
