FAQs
- Can I run primers-only PCR templates?
Yes; ensure the template contains a T7 promoter upstream of the target. - Is the enzyme compatible with CleanCap® analogs?
Fully compatible; follow supplier-recommended cap analog:NTP ratios. - How do I increase RNA yield further?
Consider adding Inorganic Pyrophosphatase (EZ0035) to remove inhibitory pyrophosphate.
