Recombinant antibodies at Miltenyi Biotec
As an innovation-powered company with a commitment to quality and excellence, Miltenyi Biotec applies cutting-edge methods to discover and develop newer and better antibodies to satisfy both market demand and regulatory requirements.
The Miltenyi way of generating best-in-class antibodies and antibody conjugates
At Miltenyi Biotec, we opt for recombinant antibodies, which enable sequence verification and optimization for lot-to-lot consistency, making them superior to hybridoma-based antibodies.
Infusing our unique expertise
Recombinants are the result of combining genetic material from different immunized animals, and using display technologies to screen in-house antibody libraries for the best antibodies. Additional analyses on existing hybridoma-based antibodies can also give rise to sequences contributing to novel recombinants.
Maximizing value for your research
By further re-engineering these antibody sequences, we can precisely control their properties to achieve the following benefits:
reduce undesirable binding to Fc gamma receptors,
- eliminate destabilizing amino acid motifs,
- increase specific bonding affinity for stronger, more accurate targeting, and
- optimize fluorochrome conjugation for brighter and clearer signals.
In a final step, by synthesizing and cloning the resulting gene sequence, we achieve an expression vector that develops a cell line, which in turn produces a special recombinant antibody.
Better science with quality antibodies
Already in 2015, 100 of the world’s leading scientists collectively called for better standards and reproducibility in antibody production, proposing recombinant antibodies to circumvent variability (Baker, M. Reproducibility crisis: Blame it on the antibodies. Nature 521, 274–276 (2015). https://doi.org/10.1038/521274a). Moreover, by applying reverse engineering, which is encouraged by the EU Directive 2016/943 r, Miltenyi Biotec acts “[i]n the interest of innovation and fostering competition…” (§16).
Overview
Clone REA485 recognizes the human, mouse, and rat C-C motif chemokine 2 (CCL2) antigen, which is also known as monocyte chemotactic protein 1 (MCP-1) or platelet-derived growth factor-inducible protein JE. CCL2 is a member of the C-C chemokine family, and a potent chemotactic factor for monocytes. Human CCL2 is composed of 76 amino acids and is 13 kDa in size. CCL2 is produced either constitutively or after induction by oxidative stress, cytokines, or growth factors. It is produced by many cell types, including endothelial, fibroblasts, epithelial, smooth muscle, mesangial, astrocytic, monocytic, and microglial cells. These cells are important for antiviral immune responses in the peripheral circulation and in tissues. However, monocyte/macrophages are found to be the major source of CCL2. It regulates the migration and infiltration of monocytes, memory T lymphocytes, and natural killer (NK) cells. CCL2 has been implicated in the pathogenesis of diseases characterized by monocytic infiltrates, like psoriasis, rheumatoid arthritis, or atherosclerosis.
Additional information: Clone REA485 displays negligible binding to Fc receptors.
