Antibody Sequencing
Watsonbio provides convenient, rapid, reliable, and customized sequencing services for your valuable monoclonal antibodies. Our platform supports sequencing from any antibody-producing cell line, with services tailored to meet your specific needs — whether for quality control, intellectual property protection, antibody engineering, or therapeutic development. We combine speed with precision to support your downstream research and commercialization goals.
Features
● Convenient Sample Handling: Our proprietary enzyme technology enables RNA lysis at room temperature — NO DRY ICE needed. We provide both the RNA lysis buffer and a FedEx shipping label to simplify your logistics.
● Unmatched Accuracy: Bi-directional sequencing of multiple independent clones ensures highly accurate and reliable results.
● Cost-Effective & Fast: Enjoy competitive pricing without compromising on quality. We offer rapid turnaround to meet your project timelines.
● Comprehensive Reporting: Each project includes a detailed report featuring annotated antibody isotype, DNA and protein sequences, and identified CDRs.
Sample Requirements
We accept a variety of cell types, including hybridoma cells, B cells, and single B cells.
- Minimum cell count: > 2 × 10⁶ cells
- Collection: Add 500 µL of the provided RNA lysis buffer directly to your sample and place it into the included FedEx envelope using the pre-paid shipping label.
- Supported species: Mouse, rat, rabbit, ferret, and more
