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>
