Custom Antibody Production Service

Biologics International Corp (BIC) offers an extensive line of custom antibody production services, including mouse and rat custom antibodies. Our professionals work to fully understand customers’ requirements (testing, specifications, packaging, regulatory requirements), and then our scientists help researchers to produce custom antibodies per the customer’s specifications in a timely, quality-controlled, and flexible manner.

We specialize in high-quality antibodies, particularly those which are difficult to produce. Our main foci are robust screening methodologies and excellent antigen design. Antigen design and production are key factors in the successful development of a high-quality antibody. We have considerable experience in protein production and peptide synthesis.

Our antibody products are backed by a 100% satisfaction guarantee to work in diverse applications, including western blot (WB), flow cytometry (FC), immunofluorescence (IF), immunohistochemistry (IHC), immunoprecipitation (IP), as antibody-drug conjugates, and as ELISA detection antibodies (direct, indirect, sandwich, and capture ELISA formats).

Our Custom Antibody Services:

BIC provides monoclonal antibody production services, protein/peptide antigen design, and antibody labeling, among others. If the delivered antibody fails to meet the standard requirements, there will be no charge to the customer. Our internal antigen design tools ensure a high antibody production success rate and the largest natural epitope of soluble antigen. We guarantee an ELISA titer >1:128,000, a purity >90%, and positive test results in WB.

Custom Monoclonal Antibody

Biologicscorp's polyclonal antibody service is designed to supply you with custom, affinity-purified pAbs that are guaranteed to detect your antigen of choice using ELISA (titer >1:128,000) and dot blot assays. If no pAb is delivered, there is no charge.

Custom Polyclonal Antibody

W provide an antibody pairing service. Paired antibodies can bind to the same antigen at the same time and are commonly used in double-antibody sandwich enzyme-linked immunosorbent assay (ELISA). The number of immunized mice is at least 10 (basic service), and the pairing success rate is high. BIC offers complete upstream and downstream support services including antigen synthesis, preparation of monoclonal antibody, antibody pairing, and mass production of antibodies. You only need to provide antigen or antigen sequences, and BIC will deliver the paired antibodies.

Antibody Pairing

Other Antibody Service

BiologicsCorp offers additional custom antibody services, including antibody labeling, antibody purification, antibody subtype identification, and antibody affinity determination. These specialized antibody services can be further tailored to meet your custom projects and needs.

How to Select Antibodies

Two factors should be taken into consideration before the start of each project design. One is the intended application of the monoclonal, polyclonal, and single-domain antibodies. The other is the choice of host species. The following table provides advantages and disadvantages of each antibody type related to these two factors.

Antibody Information

  1. What does the customer need to submit to BIC before the start of the project?
  2. Below are some frequently asked questions about our antibody production services. Should you have any questions other than those listed below, feel free to contact us, and we will be happy to answer them.

  3. What types of antibody service does BIC offer?
  4. The standard antibody production service at BIC includes rabbit polyclonal antibody production and monoclonal antibody production. Meanwhile, other services can also be provided, such as antibody pairing, antibody labeling, antibody purification, antibody subtype identification, and antibody affinity determination.

  5. Does BIC guarantee antibody titers?
  6. Yes, our guaranteed antibody service begins with antigen design and ends with antibody purification. We guarantee the delivery of antibody titers >1:128,000 and positive WB test results. There will be no charge to the customer if these requirements are not met.

  7. What species do you provide for your antibody production service?
  8. For polyclonal antibodies, we provide two New Zealand white rabbits and for monoclonal antibodies, 5 BALB/c mice. If there is a need for other species, such as chickens, sheep, guinea pigs, rats, etc., or if immunization of additional animals is required, please contact us.
