Medchemexpress LLC NH2-PEG3-C6-Cl | 1261350-60-0 | 267.79 | 50 MG
NH2-PEG3-C6-Cl is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
- Contains two different ligands connected by a linker
- One is a ligand for an E3 ubiquitin ligase
- The other is for the target protein
Apexbio Technology LLC Ribosomal protein L3 peptide (202-222) amide 5mg
Ribosomal protein L3 peptide (202-222) amide is a synthetic peptide corresponding to residues 202 to 222 of ribosomal protein L3 with the sequence Met-Ser-His-Arg-Lys-Tyr-Glu-Ala-Pro-Arg-His-Gly-His-Leu-Gly-Phe-Leu-Pro-Arg-Lys-Arg-amide and a molecular formula of C114H182N42O25S (Mw 2573) Ribosomal protein L3 is an integral component of the large ribosomal subunit (60S) interacting with 23S rRNA to constitute the ribosome s peptidyl transferase center This particular peptide segment can bind to HIV-1 TAR RNA suggesting its role in studying TAR-mediated transcriptional activation and RNA-protein interactions in molecular virology research
