Gold Biotechnology Inc Guanidine thiocyanate (Guanidine Isothiocyanate) 1 kg
During cell lysis and the extraction of DNA or RNA, denaturing enzymes such as DNase and RNase are released. To prevent DNA or RNA denaturation, the chaotropic agent, Guanadine thiocyanate is the preferred agent for use during cell lysis, and for DNA or RNA extraction. This is because of its strong ability to irreversibly inhibit the activity of DNase and RNase.
Medchemexpress LLC PC-Biotin-PEG4-NHS carbonate | 2055198-03-1 | 810.87 | 50 MG
PC-Biotin-PEG4-NHS carbonate is a PEG-based PROTAC linker used in the synthesis of PROTACs. PROTACs consist of two different ligands connected by a linker; one ligand is for an E3 ubiquitin ligase and the other is for the target protein. PROTACs utilize the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
- PEG-based PROTAC linker
- Used in the synthesis of PROTACs
- Exploits the intracellular ubiquitin-proteasome system
- Selectively degrades target proteins
