A1: It is a mixture of PCR products. Q2: How do I choose the right DNA Marker? A2: Simply ensure that the size of your target band falls within the range of the smallest and largest bands of the DNA Marker for accurate size reference. Q3: Is this Marker suitable for PAGE gels? A3: This Marker is designed for agarose gel electrophoresis. It has not been tested in PAGE gels. Q4: Can I use a DNA marker for RNA electrophoresis? A4: It depends on the gel type. For denaturing gel electrophoresis, using a DNA Marker is not recommended as the double strands will separate. For standard agarose gel electrophoresis, a DNA Marker is not accurate for determining RNA size, but it is acceptable for a rough estimation. Q5: The DNA marker bands are not resolving well and appear severely curved/bowed? A5: Possible causes: a) Voltage is too high; b) YeaRed nucleic acid stain was added when the agarose was still too hot. Solutions: Adjust the voltage to 110-130V and run for at least 45 minutes. Allow the melted agarose to cool until it is no longer hot to the touch before adding the YeaRed stain. Q6: The DNA Marker looks good, but my sample bands are curved? A6: This is likely due to sample overloading. Solution: Reduce the sample loading volume. Q7: Why are the small molecular weight bands of the DNA Marker weaker? A7: This is a normal phenomenon. Cationic (positively charged) nucleic acid stains migrate in the opposite direction to nucleic acids in an electric field. Since small DNA fragments migrate faster and are ahead of the stain, they bind less dye, resulting in weaker fluorescence.
