Molecular ecology – lab results 23.05.2024 Cytochrome B amplicons Top row: ladder, samples 1-8, negative control Bottom row: ladder, samples 9-16, negative control (applied twice, which is not necessary) Sample 4 and 8 seem to be faint, however this is most likely due to a somewhat spilled sample (on the gel) rather than to little PCR product. Negative controls don’t show any signal – good!
