Unique Conjugation Technology
HoneyBear Biosciences' proprietary conjugation belongs to the new generation of site-specific conjugation technology. The core technology utilizes glycan conjugation.
| Specificity | Advantage |
|---|---|
| Precisely Conjugation site and conjugation ratio | Efficacy, stability and safety increase |
| No antibody sequence mutation is needed | Time and cost effective |
| Can Conjugate Two different payloads | Wider application, efficacy and response rate increase, resistance decrease |
| ADC products are more homogeneous | Efficacy, stability and safety increase |
| Exhibit high yield conjugation with easily purified | Time and cost effective |
Facile dual-payload synthesis
Combination of Different MOA Payloads
