The Value of Antibody Sequencing

Sequencing an antibody allows researchers to determine the exact genetic sequence of its heavy and light chains. This information can be used to produce recombinant antibodies, providing a consistent, renewable source of the same antibody – even if the original cell line is lost or unstable.

Recombinant antibodies are useful for ensuring consistent results, scaling up production, and enabling further modifications. This service helps researchers to maintain reliable access to important antibodies for ongoing and future research.

Antibody Sequencing FAQs

Do you need access to the original cell line for sequencing?

No. Our de novo antibody sequencing platform works with IgG antibodies, and does not require access to the original cell line.

What do you need for sequencing?

We require 200µg of monoclonal antibody at ≥90% purity for sequencing. If you require recombinant antibody production, we also need 50µg of antigen ≥90% purity for ELISA detection.

Can you identify all amino acids, including isoleucine and leucine?
Yes. With 200µg of antibody at ≥90% purity, we can identify all amino acids and accurately distinguish between isoleucine and leucine.

What is your sequencing accuracy and coverage?
We guarantee 100% accuracy and full coverage of the desired VH and VL domains.

How long does the sequencing process take?
Standard sequencing turnaround is as fast as 2–3 weeks.

Can you produce a recombinant antibody from the sequence?
Once sequencing is complete, we can produce a recombinant antibody with binding affinity verified by ELISA.

What is included in the antibody sequencing and recombinant antibody production package?
The full package includes antibody sequencing with a 100% coverage guarantee, followed by recombinant antibody production and binding affinity detection by ELISA. You will receive antibody sequencing data, a coverage map, 1 mg of recombinant antibody at ≥90% purity with ELISA-verified binding, and 4µg of plasmid containing the gene insert. You can find more information about our custom recombinant antibody production here.

Do you offer a guarantee for your services?
Yes. Our risk-free guarantee includes a guaranteed antibody sequencing result – or it’s free of charge

Please can you provide details of your pricing and packages?

Absolutely. You can download our packages, including estimated turnaround times, here

Custom Protein Expression Services

“We had concerns about hydrophobic proteins with poor solubility. Biomatik started from codon optimization and gene synthesis, and the resulting proteins had significantly improved solubility. In our ELISA assays, they showed high specificity and low background. Excellent quality, fast turnaround, and helpful support—highly recommended.”

Custom Antibody Production Services

“I work on molecular farming, producing recombinant protein in plant suspension cells. I'm completely satisfied after almost 5 years of ordering antibodies at Biomatik. Perfect reproducibility batch after batch, and I hope to continue like this!”

“We are very satisfied with the peptide antibodies you produced. They work exceptionally well for both WB and immunostaining—strong and specific signals. Your pricing, service, and timelines are excellent. I will definitely continue using your service.”

Custom Gene Synthesis Services

“Different groups here have found your service excellent. That’s why another group also decided to go with Biomatik—it came highly recommended.”

“We received the antibody and it works very well! I’m extremely happy with it. We’ll definitely contact you for future antibody projects.”

"I'm very happy with Biomatik, because we have had good results with our protein expression. The service is fast and high quality compared with other companies.”

Custom Peptide Synthesis Services

“I’ve ordered many peptides from Biomatik over the past two years. Every experience has been smooth—thanks to their great customer service and unbeatable prices. I’ll continue choosing Biomatik for all my peptide orders.”

“I’ve used several companies for peptide synthesis, and Biomatik has been the best. Their prices are competitive—half the cost of some others—and the customer service is top-notch. Ordering is quick and pain-free.”

Custom Antibody Production Servicdes

“Biomatik has generated several primary antibodies for me over the past 8 years. All performed beautifully in WB and IH/IF. I’m extremely pleased with their outstanding service, work ethics, and professionalism. Production was always on time and delivered as quoted. I will definitely return for future antibody needs.”

“We ordered polyclonal antibody production using synthetic peptides and received everything on schedule. The antibodies produced strong, specific signals and integrated seamlessly into our experimental protocols. An excellent experience.”

Let customers speak for us

from 222 reviews

We were very pleased with Biomatik’s performance on a custom recombinant protein project earlier this summer. Communication throughout the project was excellent, technical questions were addressed promptly, and the supporting analytical and QC data were clear and comprehensive. The recombinant protein was produced to the requested specifications and delivered on schedule. Based on this experience, we have chosen Biomatik for an additional custom protein production project and would be pleased to work with them again.
