About Dmitry Kuksin

A Ph.D. graduate from the Department of Microbiology with a concentration in Virology. My studies have focused on Simian Virus 40 (SV40), a polyomavirus, its entry, trafficking, and pathway to infection. The focal point of my research has been the detection and tracking of input SV40 genomes from the endoplasmic reticulum to the host cell nucleus.

Evaluating Anticancer Drug Compounds using Image Cytometry

Image-based, automated analysis of 3-D tumor spheroids in microwell plates is becoming standard practice for the evaluation of anticancer drug compounds.

Celigo Helping Move Research Forward to Find a Cure for Alzheimer’s

November is National Alzheimer's Disease Awareness Month and research into a cure for the disease is vigorous. In a recently published paper "CRISPR/Cas9-Correctable mutation-related molecular andphysiological phenotypes in iPSC-derived Alzheimer’s PSEN2N141I neurons" researchers used the Celigo image cytometer upstream of CRISPR/Cas9 to visualize and asses cell death related to the sensitivity of iPSC-derived PSEN2N1411 neurons in the presence of Aβ42 oligomer toxicity.

Fast, accurate analysis of yeast, platelets, algae and other small cells

Acquire Fast, Accurate and Consistent Cell Viability and Concentration Measurements of Small Cells (2 microns or greater)! Obtaining consistent viability and concentration measurements for small cells like yeast, platelets or algae can be challenging. The Cellometers X1 and X2 can both perform bright-field and fluorescent counting of cells 2 microns and greater. X1 and X2 Cellometers are equipped with a 10X magnification lens. Both are capable of providing consistent concentration and viability measurements for cell samples that are 2 microns in size and greater. Both instruments are routinely used in laboratories around the world interested in studying small cells. See [...]

Impact of RBC contamination in clinical samples

Bone marrow, cord blood, whole blood, and peripheral blood are routinely processed in many different laboratories. Whether for cryopreservation or for downstream isolation of specific nucleated cells, (such as stem cells, B-cells, or T-cells) accurately measuring cell concentration and viability is paramount to the overall success of the project. Many blood-based samples (whole blood, peripheral blood, bone marrow, PBMC, cord blood, etc…) may contain residual red blood cells even after RBC lysis. (See figure below) When samples are enumerated using manual counting, the presence of residual RBCs can lead to inaccurate cell concentration and viability readings. Nucleic acid dyes, acridine [...]

Video Presentation: Using Cellometer Image Cytometry to Detect and Measure GFP Expression Efficiency

This presentation will focus on using Cellometer image cytometry to effectively determine GFP or other fluorescent protein transduction/transfection efficiency and cell concentration, as well as detect and quantify dual expression in a cell population. Quantifying GFP can be done in four easy steps. First pipette 20 ul of target cell sample into a disposable counting chamber. Then insert the slide into the instrument, select your assay from the drop-down menu, focus and click count. Within seconds the instrument acquires images, identifies cells with and without fluorescence and automatically tabulates the results. The results include the number of cells counted in [...]
