R-M2-9933	Biotin-L-Threonine	Biotin-L-Threonine is a biotinylated amino acid conjugate.It is widely used as a biotin tag, affinity probe, or building block for bioconjugation, peptide synthesis, and nanocarrier surface modification, especially when a slightly more sterically hindered and hydrophilic linker is desired compared to serine.	price>
R-M2-9934	Biotin-L-Tryptophan	‌Biotin-L-Tryptophan‌ is a bioconjugate formed.This compound combines the high-affinity binding properties of biotin to streptavidin/avidin proteins with the functional characteristics of tryptophan, including its role in protein structure and UV absorbance. ‌Applications:‌ ‌Biotinylation of proteins/peptides‌ for affinity-based assays. ‌Fluorescence/quenching studies‌ (intrinsic fluorescence of tryptophan). ‌Drug delivery‌ (biotin-targeted systems).	price>
R-M2-9935	Biotin-L-Histidine dihydrochloride	Biotin-L-Histidine Dihydrochloride is a water-soluble compound.This compound is widely used in ‌proteomics, drug delivery, and bioorthogonal chemistry‌. ‌Applications:‌ ‌Biotinylation‌: Conjugation to proteins/peptides for streptavidin-based detection. ‌His-tag alternatives‌: Used in purification or labeling alongside Ni-NTA systems. ‌pH-responsive systems‌: PKa (~6.0) of Histidine enables controlled release in endosomal environments.	price>
R-M2-9936	Biotin-L-Cysteine	Biotin-L-Cysteine (Biotinylated L-Cysteine) is a bioconjugate formed by linking biotin to the thiol group (-SH) of L-cysteine, enabling versatile applications in biochemical research and diagnostics.	price>
R-M2-9937	Biotin-L-Proline	Biotin-L-Proline is a bioconjugate.This compound combines the high-affinity binding properties of biotin to streptavidin/avidin with the specific recognition capabilities of proline, which is critical in collagen stabilization and protein folding‌. Applications‌: Used in pull-down assays to capture proline-rich proteins or collagen fragments‌. Serves as a tool for studying proline-specific endopeptidase activity in microbial systems.	price>
R-M2-9938	Biotin-L-Lysine	Applications:‌ ‌Protein labeling‌: Biotinylation of antibodies, peptides, or enzymes for ELISA, Western blotting, or flow cytometry. ‌Streptavidin-based assays‌: Used in pull-down assays, biosensors, or super-resolution microscopy (e.g., STORM/PALM). ‌Cell surface tagging‌: Conjugation to membrane proteins for live-cell imaging or sorting.	price>
