| Fmoc-Lys(Biotin)-OH | Fmoc-Lys(Biotin)-OH is a lysine derivative [1]. Uses: Scientific research. Group: Peptides. CAS No. 146987-10-2. Pack Sizes: 1 g; 5 g; 10 g; 25 g. Product ID: HY-W010721. |  |
| Fmoc-Lys(biotin-PEG12)-OH | Fmoc-Lys (biotin-PEG12)-OH is a Lysine embedded biotinylation reagent containing a carboxylic group. Reaction of carboxylic with primary amino (-NH2) forms stable, irreversible amide bonds. The Fmoc group can be removed under basic condition to obtain the free amine which can be used for further conjugations. The hydrophilic PEG spacer arm imparts water solubility that is transferred to the biotinylated molecule. Please contact us for GMP-grade inquiries. Grade: 0.98. Molecular formula: C58H91N5O19S. Mole weight: 1194.5. |  |
| Fmoc-Lys (biotin-PEG4)-OH | Fmoc-Lys (biotin-PEG4)-OH is a polyethylene glycol (PEG)-based PROTAC linker. Fmoc-Lys (biotin-PEG4)-OH can be used in the synthesis of a series of PROTACs. CAS No. 1334172-64-3. Molecular formula: C42H59N5O11S. Mole weight: 842.01. | |
| Fmoc-Lys(biotinyl-ε-aminocaproyl)-OH | A modified lysine derivative for the preparation of biotin-labeled peptides by Fmoc SPPS., in which the biotin is separated from the lysine side-chain by a 6 C-atom spacer. Uses: Peptide synthesis. Additional or Alternative Names: Fmoc-Lys(biotinyl-ε-aminocaproyl)-OH, N-α-Fmoc-N-ε-(biotinylcaproyl)-L-lysine. Product Category: Amino Acids. CAS No. 160158-05-4. Mole weight: 707.88. Product ID: ACM160158054-1. Alfa Chemistry ISO 9001:2015 Certified. | |
| Dde-Lys(Fmoc)-OH | Quasi-orthogonally-protected Lys derivative. The Fmoc group can be removed selectively by treatment with piperidine; the Dde group is cleaved with 2% hydrazine in DMF. When removing Dde in the presence of allyl-based protecting groups, allyl alcohol should be included in the deprotection solution to prevent reduction of the allyl group. Also available Fmoc-Lys(Dde)-OH 852057. This derivative has been employed in Fmoc SPPS to facilitate the introduction of biotin to the side-chain of lysine. Uses: Peptide synthesis. Additional or Alternative Names: Dde-Lys(Fmoc)-OH, N-α-1-(4,4-Dimethyl-2,6-dioxocyclohex-1-ylidene)ethyl-N-ε-Fmoc-L-lysine. Product Category: Amino Acids. CAS No. 156648-40-7. Mole weight: 532.63. Product ID: ACM156648407. Alfa Chemistry ISO 9001:2015 Certified. | |
