Proteins
Advance functional biology, assay development and protein characterization with Biorbyt's broad portfolio of recombinant, active and native proteins, cytokines, enzymes, biotinylated proteins, peptides, immunogens, protein ladders and cell lysates.
Select from multiple expression systems, species and formats to support cell culture, binding studies, immunoassays, biochemical analysis and protein validation workflows.
Active Proteins
Functionally validated proteins designed for cell-based assays, receptor studies, pathway analysis and other workflows where measurable biological activity is essential.
Cytokines & Growth Factors
Bioactive signaling proteins for immune-cell studies, stem-cell culture, organoid workflows, proliferation, differentiation and cellular response analysis.
Human Full-Length Membrane Proteins
Explore highly purified, soluble human full-length membrane proteins designed to retain native conformation and functional activity.
Biorbyt’s Synthetic Nanodisc platform provides detergent-free, MSP-free membrane proteins for binding studies, immunization and functional assays.
Reliable proteins for reproducible biological research
Protein performance depends on more than concentration alone. Purity, folding, post-translational modification, expression system, endotoxin level and biological activity can all influence experimental outcomes.
Biorbyt's protein portfolio is designed to support researchers across discovery, assay development and validation workflows by providing clearly defined formats and application-relevant product information.
- Recombinant and native protein formats for different experimental requirements
- Bioactive proteins for functional and cell-based assays
- Multiple expression systems, species and tag options
- Cytokines and growth factors for cell culture and signaling studies
- Biotinylated proteins, peptides and immunogens for detection, interaction and antibody-development workflows
- Enzymes, standards, ladders and lysates for analytical workflows
Native Proteins
Proteins isolated from biological sources to preserve naturally occurring structure, processing and post-translational modifications where these features are important.
Biotinylated Proteins
Biotin-labelled proteins for sensitive detection, immobilization and interaction studies in ELISA, flow cytometry, SPR, BLI and streptavidin-based assays.
Peptides
Synthetic peptides for antibody blocking, epitope mapping, assay standards, protein-interaction studies and other targeted research applications.
Immunogens & Antigens
Protein and peptide antigens developed for antibody production, immunoassay development, immune-response studies and target-specific validation workflows.
Cell Lysates
Prepared cell and tissue lysates containing native protein mixtures for western blot controls, assay validation, expression studies and comparative proteomics.
Protein Ladders
Molecular-weight standards for SDS-PAGE and western blot workflows, supporting clear band-size estimation and consistent gel-to-gel comparison.
How to choose the right protein format
Match the product format to the biological question, assay design and required quality attributes before ordering.
Research Need | Recommended Category | Key Selection Points |
|---|---|---|
Binding, structural or assay-development work | Check expression system, sequence range, tag position, purity and molecular weight. | |
Functional or cell-based assay | Confirm biological activity data, carrier proteins, endotoxin level and formulation. | |
Cell growth, differentiation or immune signaling | Review species activity, unit definition, carrier content, sterility and reconstitution conditions. | |
Catalytic or biochemical assay | Check specific activity, cofactors, buffer compatibility, substrate and storage stability. | |
Preservation of native modifications | Confirm biological source, purification method, native state and lot-specific specifications. | |
Immobilization or sensitive interaction assay | Review biotinylation method, labelling ratio, activity retention and streptavidin compatibility. | |
Epitope mapping, blocking or assay standards | Check sequence, purity, modifications, conjugation status and solubility requirements. | |
Antibody generation or antigen-specific validation | Confirm antigen type, species, sequence coverage, carrier conjugation and intended immunization use. | |
Western blot control or expression profiling | Select relevant species, tissue or cell type, treatment status and total protein concentration. | |
Molecular-weight estimation | Choose the required molecular-weight range, pre-stained format and gel or blot compatibility. |
