多乐彩规律:Rabbit Monoclonal Antibody Production Service

Rabbit Mab Production Service Introduction

Rabbit mAb usually has higher affinity and specificity than mouse mAb, it can recognize more novel epitopes and mouse antigens, and plays a key role in the development of therapeutic drug candidates and diagnostic kits. Sino Biological develops rabbit mAb by constructing antibody library to directly obtain antibody genes and their sequences, which is more suitable for the long-term preservation of excellent antibodies and their recombinant expression.

Case Presentation of Rabbit Mab Production Service

江西体彩11选5多乐彩走势图今天 www.phcnlx.com.cn Sino Biological Inc. has established a high-throughput rabbit monoclonal antibody development & production technology platform. Rabbit monoclonal antibodies independently developed by this platform have better affinity and antigen detection limit than traditional mouse monoclonal antibodies.

The rabbit Mab developed by Sino Biological Inc. can be validated by multiple assay platforms, such as ELISA, WB, IHC, FACS, et al., and can be tested by multi-tissue and multi-cell. All those verification aims to improve the screening success rate of low background and high sensitivity antibodies.

a）Multi-cell, multi-tissue validation
