About PerKit® Product Line 

While many companies offer "bioconjugation kits," these often include only one or two basic reagents for generic biochemical labeling. Kits like fluorescent dye labeling kits, for instance, usually contain only a reactive dye, leading to limited functionality and customer frustration with incomplete results. 

PerKit® (Personalized Bioconjugation Kit) is CellMosaic’s high-quality, customizable product line, first introduced in 2016 and continually enhanced to meet unique bioconjugation needs for various biomolecules. Built on CellMosaic’s proprietary bioconjugation processes, PerKit® provides customers a complete, cost-effective solution for frequent or large-volume conjugations. 

Key Features of PerKit® 

  • Customizable: Each molecule has unique requirements; PerKit® is tailored to meet them with made-to-order options, including user manual adjustments based on customer needs. 
  • Validated Processes: Linkers, spacers, and chemistries are thoroughly tested and come with sample data to ensure reliability. 
  • Quality Assurance: Purification accessories are included for high-quality final conjugates. •User-Friendly: Kits come with all necessary reagents (excluding the molecule to be labeled), and most conjugations can be completed in one day. 
  • Exceptional Support: Comprehensive support is available throughout the process, with additional analysis services available. 
  • Continuous Improvement: Customer feedback drives ongoing enhancements in composition, processes, and user documentation. 

Since its launch, PerKit® has gained quick adoption. As of August 2024, CellMosaic offers around 40 PerKit® products. Highlights from the product line include:
