Our Products
Protein
A comprehensive collection of natural, active, and recombinant proteins to power your research from discovery to validation. With over 12,000 recombinant proteins and 750+ active proteins, we deliver the quality and variety you need.
Antibody
Covering polyclonal, monoclonal, recombinant, and small molecule antibodies for diverse detection and targeting applications. Our portfolio includes antibody pairs, labeled controls, and more to support consistent, reproducible results.
Kits
Ready-to-use kits streamline ELISA, exosome isolation, apoptosis detection, cell analysis, and antibody isotyping workflows. Designed for accuracy and ease, they help you get reliable data faster with less hands-on time.
Active Protein
High-quality active proteins with verified bioactivity to support your functional assays and drug discovery projects. Each batch undergoes strict quality control to ensure purity, stability, and consistent performance.
Our Service
Protein Expression Service
Reliable protein expression services help you obtain high-yield, functional proteins for drug discovery and assay development. We offer flexible scales from lab to production, ensuring fast turnaround and consistent quality.
Custom Antibody Service
Custom antibody production generates high-affinity antibodies tailored to your specific antigens, saving months of in-house effort. Our end-to-end service covers immunization, screening, and purification for reproducible results.
Single B Cell Screening Service
Single B cell screening directly isolates antigen-specific antibody sequences to accelerate therapeutic antibody discovery. This approach preserves native heavy-light chain pairing and reduces lead time significantly.
Custom Nanobody Service
Custom nanobody service delivers small, stable, and high-specificity nanobodies against challenging targets such as GPCRs or ion channels. Our platform ensures rapid hit identification and excellent expression in various systems.
Phage Display Service
Phage display screening explores billions of peptide or antibody variants to identify high-affinity binders for your target. Our robust service combines library diversity, proven protocols, and detailed biopanning reports.
Stable Cell Line Production
Stable cell line development provides high-titer, long-term production of recombinant proteins or antibodies. We prioritize clonal selection, regulatory-friendly documentation, and scalability from R&D to commercial needs.
