Explore our high-quality proteins and cell lines, designed to help you solve key research challenges in antibody validation, functional genomics, and proteomics.

Our recombinant proteins, including cytokines, growth factors, and bioactive proteins, are rigorously validated for purity and biological activity, ensuring consistent performance in assays. Our CRISPR KO cell lines, developed in physiologically relevant models, are confirmed at both genomic and proteomic levels, and paired with wild-type controls for robust comparative analysis.

Our protein and cell line range is backed by advanced validation and expert support, so you can produce reliable results and move your research forward.

Recombinant proteins

Recombinant proteins are laboratory-engineered proteins that enable the controlled and scalable production of proteins with consistent quality and functionality. We offer a broad range of recombinant proteins, including enzymes, signaling proteins, and other proteins, produced using advanced expression and purification techniques. These proteins provide researchers with consistent performance, enhancing the reproducibility of experimental results.

Our catalog includes both tagged and untagged proteins, catering to various experimental requirements and helping researchers accelerate discoveries and gain deeper insights into complex biological systems.

Cytokines and growth factors

Cytokines and growth factors play a crucial role in driving cell signaling, immune responses, and development. We offer a wide range of highly active, purified proteins optimized for bioassays and functional studies. These reagents are ideal for shaping cellular environments in cell culture and organoid experiments, supporting research into growth, differentiation, and response mechanisms. With rigorous validation for activity and purity, our products deliver reliable, reproducible results you can trust.

Bioactive proteins

Our bioactive proteins are ready-to-use and verified for biological activity, ideal for functional assays, drug target studies, and protein interaction analysis. Designed to reflect native structure and function, they deliver reliable, physiologically relevant data to accelerate your research. At Abcam, we prioritize quality and performance, making these proteins ideal for high-stakes research and development.

Peptides and blocking peptides

Our synthetic peptides and blocking peptides are designed to support antibody validation and protein interaction studies. Use them to confirm binding specificity, map epitopes, and reduce background in immunoassays. With high purity and consistent performance, our peptides help you generate clearer, more reliable data in complex experiments.

Cell lines

We offer an extensive selection of high-quality knockout cell lines, encompassing various species, cell types, and genetic modifications, to support a broad range of research applications. These cell lines undergo comprehensive quality control processes to ensure consistent performance and quality, enabling researchers to obtain dependable and repeatable results.

Lysates

Our lysates are prepared from well-characterized cell lines and tissues, offering a rich mix of native proteins for use as controls or in protein expression studies. Ideal for western blotting, mass spectrometry, and comparative analysis, our lysates deliver consistent and reproducible results to support your research from validation to discovery.
