PC Linker (photocleavable)

PC Linker (photocleavable)

Photocleavable Linker (PC Linker) often used in the design of multi-functional single-stranded nucleotide conjugates for the selection of novel DNA or RNA-based catalysts in vitro. Photocleavable PC linker modified oligonucleotide are demonstrated in Bruker Daltonik's genoSNIP, a MALDI-TOF MS based assay system for SNP detection.

Photocleavable  PC linker contained a non-nucleosidic group that can be used to link two nucleotide sequences through a short, UV photo-cleavable C3 spacer arm. Upon irradiation by UV light, photo-cleavage released oligonucleotide contain a 5-phosphorylated group with greater hybridization affinity for a complementary DNA strand than PC spacer.

Photocleavable PC linker can be incorporate at any position within an oligonucleotide. Contact Bio-Synthesis for service details.

XX-15A uv lamp 365nm 臺(tái)式紫外線燈

Cleavage Protocol：

Cleavage occurs by irradiation with near-UV light (300-350 nm, complete cleavage occurs within 5 minutes. Try using a XX-15A UV lamp at a distance of 15 cm (emission peak 365 nm, 300 nm cut-off, 1.1 mW intensity at~31 cm).

紫外線燈用于基因編輯

研究發(fā)現(xiàn)crRNA-c對(duì)核酸內(nèi)切酶降解具有極端穩(wěn)定性，卻會(huì)在輻照度為20 mW/cm2的365nm UV光照射下，在30秒內(nèi)釋放出線性crRNA，這為響應(yīng)性CRISPR編輯提供了一個(gè)極好的響應(yīng)窗口。通過更進(jìn)一步的研究發(fā)現(xiàn)，這種技術(shù)應(yīng)用于CRISPR-Cpf1系統(tǒng)也是可行的，這意味著他們的光激活環(huán)狀gRNA策略是調(diào)控RNA-引導(dǎo)的CRISPR編輯的通用方法。
