Service Advantages
● Optimal germline sequences: suitable for phage display, high expression, and good druggability
● Randomization strategy: Trimer primers, diverse CDR3 lengths, and diverse amino acid distribution
● Optimal library capacity: Library capacity close to 10 11 Good diversity, reduced ineffective screening
● Widest application: Verified by dozens of targets, suitable for different types of targets, affinity reaching pM
