Invitrogen Qubit 4 and RNA Quantification and Qualification
The Qubit quantification platform continues to evolve right along with you, offering:
- Qubit assay dyes bind selectively to DNA, RNA, or protein, making it more sensitive than UV absorbance
- Uses as little as 1 μL of sample, even with very dilute samples
- Fast, reliable detection of degraded RNA with the new Invitrogen Qubit RNA IQ Assay
- New integrated reagent calculator to quickly generate working solution calculations
