Monoclonal antibody sequencing includes hybridoma cell line sequencing and clonal B cell sequencing. Both of these kinds of cells can produce a single antibody against a unique antigen after screening. Synbio Technologies uses 5’RACE and Sanger sequencing technologies to provide both accurate and efficient hybridoma/clonal B cell sequencing services across a variety of species. We provide a fast and easy way to sequence your hybridoma antibodies, which will help you identify the best therapeutic leads for future drug development.
Standard Antibody Variant Region PCR Amplification Primers Design
mRNA isolated from hybridoma samples is subjected to RT-PCR with unique species-specific primer sets to amplify the target regions. Synbio Technologies’ antibody variable region sequencing service has identified more than 10,000 hybridoma cell lines. More than 95% of the samples have been successfully sequenced with both the heavy chain and light chain identified. Even with technically difficult samples, Synbio Technologies’ approach has demonstrated a high success rate in numerous cases. Synbio Technologies’ service, coupled with online data tracking and management system, provides customers with absolute confidence at every step.
Following the successful cloning of variable regions, the sequences can be fused to a variety of IgG or IgM backbones. Alternatively, variable region sequences can be reformatted as scFv or bispecific antibodies in various configurations. Transiently produced antibodies can then be validated and characterized by downstream analytical services.
- Comprehensive: Sequencing of heavy and light variable regions or full-length of antibody sequences.
- Wide applicability: Relying on a professional immunogenetics database and our rich experience in antibody sequence analysis and design, antibodies from any species (mouse, rat, human, rabbit, hamster, camel, sheep, etc.) and various antibody subtypes (IgG1, IgG2a, IgG2b, IgG3, IgG4, IgM, IgE, IgA etc.) can be designed and sequenced.
- Reliability: At least 4 positive clones are selected for Sanger sequencing and sequence analysis is performed to exclude any invalid sequences.
- High-throughput + great savings: Whether one or many samples, we can do it all. We provide volume discounts; meaning, the more samples you provide, the more money you will save!
- Fast turnaround time: We provide express sequencing services, as fast as one week.
- One-stop service: We provide a one-stop solution from hybridoma sequencing to recombinant antibody production. For the non-human antibodies, our antibody humanization service can be considered.
Cell Sample Preparation and shippping
- For hybridoma cell lines or clonal B cells: customers will need to submit hybridoma cell samples (>1×106 cells) and indicate the species and subtype of the monoclonal antibody.
- There are two options for the shipping:
I: fresh cells in frozen vial(s) and ship in dry ice.
II: washed cells with PBS and re-suspend the cells in 5–10 volumes (0.2ml~0.5ml) RNAlater Solution, then ship with blue ice.
