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 REA989 recognizes the human and mouse AN2 antigen. AN2 is the mouse homolog of the rat NG2 and human Melanoma (MCSP) proteins. NG2 is a chondroitin sulfate glycoprotein that is expressed by glial progenitor cells in the developing and adult central nervous system (CNS) and by immature Schwann cells. NG2/AN2+ glia has been identified as a fourth major glial cell type in the mammalian CNS that is distinct from other cell types. NG2/AN2+ cells are precursors of oligodendrocytes and some protoplasmic astrocytes in the gray matter. NG2/AN2 expression is down-regulated before the cells undergo terminal differentiation. However, a population of NG2/AN2+ cells remains in the white and gray matter after oligodendrocytes are generated. NG2/AN2+ glial cells participate in neuron-glial circuits by receiving presynaptic input from neurons and responding to neurotransmitters released by synapses. Many highly migratory neural tumors including melanomas express NG2/AN2.
