IMMUNOSTEP is a Biotech company focused in the proteomic area that research, develop, produce and market reagents and technologies both for research and diagnostics based on techniques such us Flow cytometry, Cell Culture, Western Blot and others. IMMUNOSTEP scientific team has extensive expertise in monoclonal and policlonal antibody development (mouse, rabbit and chicken), as well as in the product quality control for research and diagnosis. 

Our product areas include human and mouse cell immunophenotyping, human recombinant proteins, apoptosis, cytokines and growth factors, cell-cycle analysis, detection and quantification proteins.


  Immunostep has long been working to find and develop the best antibodies for Flow Cytometry. This has allowed us to obtain monoclonal antibodies that afford a better fluorescence intensity than other products available on the market.
Moreover, Immunostep subjects all its antibodies to stringent testing such as repeatability, diagnostic sensitivity, analytical sensitivity or linearity, specificity and titre, thereby guaranteeing that all its products are suitable fordiagnosis and research.


 Apoptosis ("normal" or "programmed" cell death) is the physiological process by which unwanted or useless cells are eliminated during development and other normal biological processes.

Flow Cytometry Solution


Immunostep, a leading provider of technologies, tools, and services for bioscience research and biopharmaceutical manufacturing, offers of a range of assays, kits and solution for flow cytometry. Flow cytometry is a powerful method used to measure cell numbers, cell viability, programmed cell death (apoptosis), cell division, toxicity, and the differential expression of specific proteins that can help scientists understand the biology of embryonic development, cancer, metabolic and degenerative diseases, drug effects, and even aging


  Immunostep has high quality products for Clinical Research include Kits as ThromboStep.
