apo 2

Cyclic di-UMP is a pyrimidine-containing cyclic dinucleotide (CDN).1It is produced by bacterial cGAS DncV-like nucleotidyltransferases (CD-NTases), such as LpCdnE02 fromL. pneumophila, and binds to cGAS, in the apo or dsDNA-bound forms, with reduced affinity compared to 2'3'-cGAMP or 3'3'-cGAMP .1,2Cyclic di-UMP is intended for use as a negative control for cyclic di-GMP signaling. 1.Whiteley, A.T., Eaglesham, J.B., de Oliveira Mann, C.C., et al.Bacterial cGAS-like enzymes synthesize diverse nucleotide signalsNature564(7747)194-199(2019) 2.Hall, J., Ralph, E.C., Shanker, S., et al.The catalytic mechanism of cyclic GMP-AMP synthase (cGAS) and implications for innate immunity and inhibitionProtein Sci.26(12)2367-2380(2017)

Cas9-IN-2 是一种 Cas9 的有效抑制剂，其 IC50 值为 246 μM。Cas9-IN-2 能够结合 apo-Cas9，进而防止 Cas9:gRNA 复合物的形成。Cas9-IN-2 能够用于调节和控制 Cas9 的活性。
