The process of attaching biotin to biomolecules, known as biotinylation, is a critical technique with widespread applications in molecular biology, diagnostics, and therapeutics. Selecting the appropriate biotinylation reagent is paramount to achieving successful and reliable results. Among the various options available, Biotin-6-aminohexanoic acid pentafluorophenyl ester (Biotin-Aca-PFP) stands out as a particularly effective and versatile choice.

NINGBO INNO PHARMCHEM CO.,LTD., a reputable supplier based in China, offers Biotin-Aca-PFP with a strong emphasis on purity, typically exceeding 98%. This high level of purity is essential for applications where even trace impurities can interfere with experimental outcomes or lead to false positives. The pentafluorophenyl ester group makes Biotin-Aca-PFP a highly reactive agent for labeling molecules that contain primary amine groups. This efficient reaction profile is a key reason for its popularity in advanced molecular labeling and bioconjugation strategies.

The chemical structure of Biotin-Aca-PFP is carefully designed for optimal performance. The aminohexanoic acid (Aca) spacer arm provides adequate distance between the biotin moiety and the conjugated biomolecule, which is crucial for maintaining strong binding to avidin or streptavidin. This spacer also contributes to the overall solubility and accessibility of the biotinylated molecule. When considering reagents for peptide synthesis or protein modification, the predictable reactivity and the presence of this spacer arm make Biotin-Aca-PFP a preferred option.

For scientists in need of a dependable high purity biotinylation agent, NINGBO INNO PHARMCHEM CO.,LTD. provides Biotin-Aca-PFP as part of its comprehensive catalog of life science reagents. Its effectiveness in various conjugation chemistries, coupled with its high purity, makes it an excellent choice for researchers looking to optimize their labeling protocols. Whether for fundamental research or the development of novel diagnostic tools, the reliability of this reagent ensures that scientific endeavors can proceed with confidence.
