Product Description
AapCas12b nuclease (also known as C2c1) is derived from Alicyclobacillus acidophilus. It is a crRNA-mediated nuclease that recognizes and cleaves double-stranded DNA (dsDNA) in the presence of a PAM (Protospacer Adjacent Motif) sequence (TTN). For single-stranded DNA (ssDNA) cleavage, the PAM sequence is not required. Upon binding to complementary ssDNA or dsDNA, the trans-cleavage activity of AapCas12b on non-specific ssDNA is activated. AapCas12b has an optimal reaction temperature of 60°C, making it more heat-resistant compared to Cas13a and Cas12a. This property makes it highly suitable for field nucleic acid detection applications when combined with loop-mediated isothermal amplification (LAMP).

Reaction Conditions
Use a real-time fluorescence quantitative PCR machine or an isothermal amplification instrument to detect the fluorescence signal. The reaction should occur at 60°C, and the fluorescence signal should be collected every 30 seconds. Alternatively, the fluorescence signal can be directly observed under a UV light.
Storage Conditions and Shelf Life
The product is stable for 1 year when stored at -20°C. For long-term storage, it is recommended to store at -80°C. It is advised to aliquot the product based on the frequency of use to avoid repeated freeze-thaw cycles.
