Press note 1

Proteins are high molecular weight molecules composed of amino acids. They are the building blocks of all living organisms and play role in all their crucial functions. Due to their complexity, their production in the laboratory, demands technologies utilizing living microbes or cells. Recombinant protein is obtained by DNA recombination using variety of molecular biology techniques. It is the first step in the protein production in vitro. The subsequent ones are: protein expression (its biosynthesis in bacterial or mammalian cells) and purification (proteins chromatography).

Pure Biologics – specialized contract research organization - offers protein production and contract research services with a main focus on high quality contract protein manufacturing for preclinical studies of biological drug leads or for diagnostics development. As a company offering custom proteins we effectively respond to the needs of pharmaceutical and biotech companies, as well as research institutions, for which recombinant protein production is usually crucial for scientific objectives. Another strong branch of our services is a detailed analysis of proteins.

It often happens that not the protein downstream processing or protein purification itself is the most challenging step, but its efficient production in soluble form to maintain biological activity. Thus, Pure Biologics offers proprietary methodology allowing for protein refolding, i.e. renaturation of inactive proteins produced in insoluble form.

Currently, recombinant monoclonal specific antibodies constitute the most important group of biopharmaceuticals/biologics. The standard, classical way of antibody development is still done through animal immunization. Even though protein engineering allows for antibodies humanization, they still exhibit many side effects. Therefore, Pure Biologics offers recombinant antibody development by an alternative in vitro approach – antibody selection from libraries using Phage Display technology. Human recombinant antibodies obtained by this way are often characterized by better affinity parameters than those arising from classical methods.  

As professionals and enthusiasts, we are constantly extending our portfolio of services. Pure Biologics also offers: protein analytics, assay development, assessment of enzymatic activity, affinity measurements, protein stability measurements and protein conjugation. We mastered many proteomics approaches for protein identification, direct mass measurement and protein sequencing using mass spectrometry service (MS analysis). Pure Biologics has also long-term experience in bioinformatics analysis and genome sequencing projects.

Press note 2

Pure Biologics is a specialized Contract Research Organization & CMO with expertise on proteomics, particularly on protein engineering, efficient recombinant antibody and recombinant protein production.

The company provides a complete gene to protein service. Starting from vector construction with applicable molecular biology methods, through protein expression and protein purification using proteins chromatography we deliver pure custom proteins with the highest quality. In cases where the protein downstream processing results in getting recombinant protein in insoluble form as inclusion bodies, lacking its native structure and biological activity, the company has unique expertise in protein refolding. Together with detailed analysis of proteins and custom assay development, we offer a wide range of services to companies in the biotech and pharmaceutical industries which conduct research on biologics as potential drug candidates in preclinical studies. We mastered also methods for antibody selection through Phage Display to obtain specific antiobodies for biomedical and diagnostic use. Recombinant antibodies obtained by this way, instead of classical immunization, are often characterized by better affinity parameters.

The company is mainly focused on protein production and antibody development services. Apart from contract protein manufacturing, we provide services on protein analytics and protein conjugation. Pure Biologics offers a comprehensive range of bioanalytical protein characterization methods, including protein sequencing using mass spectrometry service (MS analysis), studies of enzymatic activity, protein stability and affinity measurements. Our team of specialists is also experienced in bioinformatics and genome sequencing projects.
