Olga Ornatsky is a Soviet born, Canadian scientist. Ornatsky co-founded DVS Sciences [1] in 2004 (acquired by Fluidigm in 2014 and then renamed to Standard BioTools in 2022 [2] ) along with Dmitry Bandura, Vladimir Baranov and Scott D. Tanner.
Ornatsky graduated from the Moscow State University, Department of Biology. In 1989, she completed her Ph.D. in Cell & Molecular Biology, [3] and worked as a Research Scientist at the Cardiology Centre studying vascular smooth muscle involvement in atherosclerosis. In 1993, she immigrated to Canada, and became a Postdoctoral Research Fellow at York University. She quickly progressed to become Senior Research Associate in the Laboratory of Vascular Biology and Cardiac Surgery at St. Michael's Hospital (Toronto). Her achievements brought her to MDS Proteomics Inc. (now Protana Inc), where she led her research group as a Senior Scientist for four years.
In 2005, she left MDS to pursue a different direction. Together with the co-founders of DVS Sciences Inc. Scott D. Tanner, Vladimir Baranov and Dmitry Bandura, she helped develop the CyTOF™ Mass Cytometer, for highly multi-parametric single cell analysis at the Department of Chemistry, University of Toronto. Olga held the position of Director of Bioassay Development at DVS Sciences, Inc. After the merger with Fluidigm Inc in 2014, she transitioned to Principal Scientist, Proteomics division, and lead a group of biology and chemistry researchers involved in developing new metal-tagged affinity reagents, as well as methods and applications for Mass cytometry until her retirement in 2019.
Ornatsky has more than fifteen years of experience in the commercial environment as a senior strategic product application developer and in providing advanced customer/collaborator support. Her primary field of expertise is in cellular and molecular biology, with the objective of developing bioanalytical assays for mass cytometry(CyTOF). Olga is a principal inventor on several patents.

Inductively coupled plasma mass spectrometry (ICP-MS) is a type of mass spectrometry that uses an inductively coupled plasma to ionize the sample. It atomizes the sample and creates atomic and small polyatomic ions, which are then detected. It is known and used for its ability to detect metals and several non-metals in liquid samples at very low concentrations. It can detect different isotopes of the same element, which makes it a versatile tool in isotopic labeling.
In mammalian cells, vinculin is a membrane-cytoskeletal protein in focal adhesion plaques that is involved in linkage of integrin adhesion molecules to the actin cytoskeleton. Vinculin is a cytoskeletal protein associated with cell-cell and cell-matrix junctions, where it is thought to function as one of several interacting proteins involved in anchoring F-actin to the membrane.
Plectin is a giant protein found in nearly all mammalian cells which acts as a link between the three main components of the cytoskeleton: actin microfilaments, microtubules and intermediate filaments. In addition, plectin links the cytoskeleton to junctions found in the plasma membrane that structurally connect different cells. By holding these different networks together, plectin plays an important role in maintaining the mechanical integrity and viscoelastic properties of tissues.
Nebulette is a cardiac-specific isoform belonging to the nebulin family of proteins. It is encoded by the NEBL gene. This family is composed of 5 members: nebulette, nebulin, N-RAP, LASP-1 and LASP-2. Nebulette localizes to Z-discs of cardiac muscle and appears to regulate the length of actin thin filaments.
β-Tropomyosin, also known as tropomyosin beta chain is a protein that in humans is encoded by the TPM2 gene. β-tropomyosin is striated muscle-specific coiled coil dimer that functions to stabilize actin filaments and regulate muscle contraction.
ArgBP2 protein, also referred to as Sorbin and SH3 domain-containing protein 2 is a protein that in humans is encoded by the SORBS2 gene. ArgBP2 belongs to the a small family of adaptor proteins having sorbin homology (SOHO) domains. ArgBP2 is highly abundant in cardiac muscle cells at sarcomeric Z-disc structures, and is expressed in other cells at actin stress fibers and the nucleus.
116 kDa U5 small nuclear ribonucleoprotein component is a protein that in humans is encoded by the EFTUD2 gene.
AS160, which was originally known as TBC1 domain family member 4 (TBC1D4), is a Rab GTPase-activating protein that in humans is encoded by the TBC1D4 gene.
F-actin-capping protein subunit alpha-2 also known as CapZ-alpha2 is a protein that in humans is encoded by the CAPZA2 gene.
Talin-1 is a protein that in humans is encoded by the TLN1 gene. Talin-1 is ubiquitously expressed, and is localized to costamere structures in cardiac and skeletal muscle cells, and to focal adhesions in smooth muscle and non-muscle cells. Talin-1 functions to mediate cell-cell adhesion via the linkage of integrins to the actin cytoskeleton and in the activation of integrins. Altered expression of talin-1 has been observed in patients with heart failure, however no mutations in TLN1 have been linked with specific diseases.
Voltage-dependent anion-selective channel protein 2 is a protein that in humans is encoded by the VDAC2 gene on chromosome 10. This protein is a voltage-dependent anion channel and shares high structural homology with the other VDAC isoforms. VDACs are generally involved in the regulation of cell metabolism, mitochondrial apoptosis, and spermatogenesis. Additionally, VDAC2 participates in cardiac contractions and pulmonary circulation, which implicate it in cardiopulmonary diseases. VDAC2 also mediates immune response to infectious bursal disease (IBD).
Cytometry by time of flight, or CyTOF, is an application of mass cytometry used to quantify labeled targets on the surface and interior of single cells. CyTOF allows the quantification of multiple cellular components simultaneously using an ICP-MS detector.
Mass cytometry is a mass spectrometry technique based on inductively coupled plasma mass spectrometry and time of flight mass spectrometry used for the determination of the properties of cells (cytometry). In this approach, antibodies are conjugated with isotopically pure elements, and these antibodies are used to label cellular proteins. Cells are nebulized and sent through an argon plasma, which ionizes the metal-conjugated antibodies. The metal signals are then analyzed by a time-of-flight mass spectrometer. The approach overcomes limitations of spectral overlap in flow cytometry by utilizing discrete isotopes as a reporter system instead of traditional fluorophores which have broad emission spectra.
Metal-coded affinity tag is a method used for quantitative proteomics by mass spectrometry that uses a metal chelate complex 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetate (DOTA) coupled to different lanthanide ions. The metal complexes attach to the cysteine residues of proteins in a sample.
Lanthanide probes are a non-invasive analytical tool commonly used for biological and chemical applications. Lanthanides are metal ions which have their 4f energy level filled and generally refer to elements cerium to lutetium in the periodic table. The fluorescence of lanthanide salts is weak because the energy absorption of the metallic ion is low; hence chelated complexes of lanthanides are most commonly used. The term chelate derives from the Greek word for “claw,” and is applied to name ligands, which attach to a metal ion with two or more donor atoms through dative bonds. The fluorescence is most intense when the metal ion has the oxidation state of 3+. Not all lanthanide metals can be used and the most common are: Sm(III), Eu(III), Tb(III), and Dy(III).
Standard BioTools Inc., previously known as Fluidigm Corp., offers analytical mass cytometry systems for flow cytometry and tissue imaging, along with associated assays and reagents, as well as an automated genomic analysis instrument and a variety of microfluidic arrays, or integrated fluidic circuits (IFCs), and consumables with fully kitted reagents. Custom assays and services are available with all systems and applications.
