What Are Recombinant Proteins?


Recombinant proteins are purified laboratory reagents produced through genetic engineering. A specific gene of interest is inserted into a host organism, such as mammalian, bacterial, yeast, or insect cells, which then expresses the protein in a controlled environment.


The recombinant process utilized to generate the recombinant proteins in our catalog provides precise control over sequence modifications, expression levels, and large-scale production tailored to experimental needs. These recombinants are widely used in research to investigate protein-protein interactions, enzyme activities, receptor-ligand binding, and cellular responses. Additionally, recombinant proteins serve as standards or controls in immunostaining assays and support cell growth and differentiation in culture systems, particularly in immunology, oncology, and structural biology studies.


Common Applications of Recombinant Proteins


  • Studying protein-protein and protein-DNA interactions

  • Functional assays to study biological pathways

  • Standard curves in ELISA and other quantitative assays

  • Use as antigens for antibody production

  • Development and screening of therapeutic drugs

  • Biomarker discovery and validation

  • Cell signaling and immune response studies

  • Vaccine research and development


Key Features of AAA Biotech’s Recombinant Proteins


  • High Purity: Most proteins are purified to ≥95% using affinity chromatography and other validated techniques.

  • Biological Activity: If functional activity is tested and confirmed for a given protein, it will be noted directly on the product page.

  • Multiple Expression Systems: Available in E. coli, HEK293, CHO, yeast, and insect cells to match your assay requirements.

  • Custom Tags Available: His-tag, GST, FLAG, and Fc fusion options for easy purification and detection.

  • Wide Range of Targets: Cytokines, growth factors, enzymes, receptors, signaling proteins, and more.

  • Validated Consistency: Lot-to-lot consistency ensured through rigorous QC protocols.

  • Flexible Quantities: Available in various pack sizes to suit different experimental needs.

  • Ready-to-Use Format: Lyophilized or liquid formulations that are easy to reconstitute and use.

FAQ


1. How are AAA Biotech recombinant proteins validated?


Each batch undergoes stringent quality control checks, including SDS-PAGE analysis, endotoxin testing (for select products), and activity assaying (for select products). Certificates of Analysis are provided with every product.


2. Are your proteins suitable for therapeutic development or only research?


AAA Biotech recombinant proteins are strictly for research-use only and are not intended for diagnostic or therapeutic purposes in humans or animals.


3. What types of expression systems do you use for recombinant protein production?


The production labs use a variety of expression platforms, including bacterial (E. coli), yeast, insect (baculovirus), and mammalian (HEK293, CHO) systems. The expression system used depends on the complexity and intended function/use of the protein.
