2X Colorimetric RT-LAMP Master Mix
Croyez 2X Colorimetric RT-LAMP Master Mix is an optimized master mix for reverse-transcription loop-mediated isothermal amplification (RT-LAMP) reactions. This product is a dual enzyme system, providing a rapid and sensitive detection in one pot.
The amplified products can be visually observed by a metal indicator for calcium, hydroxynaphthol blue (HNB). Positive reactions will appear a color change from violet to sky blue, while negative reactions won’t.

The following procedure is a general guideline for RT-LAMP reaction. To maintain an RNase-free environment, always wear disposable gloves, and use laboratory consumables and water of nuclease-free grade during the whole experiment course.
RT-LAMP reaction set-up:
1.10X LAMP primer mix
2. An overview of the reaction set-up is listed in the table below. Place all required reagents on ice. Distribute appropriate volumes into each tube before adding template.
* See Usage Notes for additional guidelines on primer/template preparation.
3. Add target RNA template to the detection tube. Gently mix the reaction thoroughly to achieve uniform distribution and avoid making bubbles.
4. Incubate at 65°C for 30-60 min.
5. After LAMP reaction complete, the enzyme can be inactivated by heating at 80°C for 10 min.
Shipping Conditions:
