Welcome to ProSci - Distributed in the UK & Ireland by Caltag Medsystems


ProSci a broad catalogue of over 30,000 research antibodies and has completed over 20,000 Custom Antibody projects.

Their in-house labs and animal facilities (USDA licensed and NIH/OLAW approved) provide an extensive array of antibody products & services, with a focus on providing the highest quality monoclonal, polyclonal, and single domain antibodies.

ProSci's expertise in antibody production, immunochemistry services, and biological research is realised through customisable services, innovative products, competitive pricing, high-quality research tools, and unparalleled technical support.

Established in 1998, ProSci is a reliable partner with over 20 years of serving the research community globally.


ProSci specialises in the production of affinity-purified peptide-specific antibodies to novel antigens in fields such as HIV, Apoptosis, Signal Transduction, Neurobiology, Autophagy, and Immunology.

Affinity-purification allows for the isolation of antibodies specific to the epitope of interest. This results in ProSci's polyclonal antibodies having the same specificity as monoclonal antibodies at a competitive price.

Single Domain Antibodies

ProSci's Single Domain Antibody products are highly valuable in fundamental research, diagnostic, and therapeutic applications.

Single Domain Antibodies (sdAbs), also known as VHH antibodies or nanobodies, are isolated from camelid heavy chain only antibodies and are comprised of only the variable domain. As such, they lack light chains, are smaller and more stable compared to conventional antibodies, yet possess fully functional antigen-binding capability.

Due to their size (approximately 15 kDa) and their longer CDR3 region, a single domain antibody is adept at reaching otherwise inaccessible epitopes that may play a crucial role in the molecular mechanisms of disease.

Research Grade Biosimilars

Beyond therapeutics, monoclonal antibodies (mAbs) shown to be effective in the clinic can help to facilitate laboratory research.

mAbs, also known as biosimilars, are useful tools to research novel therapies and uncover effective off-target applications.

With known and approved data on toxicity and efficacy, these biologics are used as benchmarks to accelerate findings from bench to clinic.

ProSci has more than 800 research-grade biosimilar antibodies available in the following research areas:

Recombinant Proteins & Peptides

ProSci's recombinant proteins are available as monomers, dimers, trimers, and multimers.

Full-length and partial-length proteins are available for control experiments, assay development, and antibody development projects.

Utilisation of E. coli, mammalian, yeast, and baculovirus expression systems with various activity assays have been performed to ensure functionality.

Applications of ProSci's recombinant proteins include CLIA, EIA, IM, Lateral Flow, and WB.

As well as recombinant proteins, ProSci also provides peptides. Match one of ProSci's peptides with a primary antibody for blocking and control experiments.
