ORANGE COUNTY, Calif. (May 11, 2024) – The Cell Lab Signaling Cytometry (Cell Lab SC) line of reagents from Beckman Coulter, Inc., offers a comprehensive set of antibodies for the detection of the phosphorylation state of signaling proteins in cells via flow cytometry.  Performing cell signaling experiments via flow enables the user to generate precise, specific and quantitative measurements of the signaling response in individual cellular subpopulations.

The reagents, which in the initial offering are conjugated to either Alexa Fluor* 488 or Alexa Fluor 647, are released in conjunction with a new method that allows analysis of samples in whole blood.  Analyzing samples in whole blood minimizes artifacts and variability introduced through sample manipulation and helps preserve the native biology of the cell.  The method has also shown excellent performance when used with bone marrow, cell culture, and purified cell populations.  

Antibodies in the Cell Lab SC line can be used in combination with extracellular markers to study signaling patterns in specific cellular subpopulations.  Products are available for the study of apoptosis, chromatin regulation, cytoskeletal signaling, DNA damage, lymphocyte signaling, MAP kinase signaling, protein folding, translation control and other phosphorylation events.

"Using flow cytometry to get quantitative, cell-type specific data enables researchers to interrogate signaling pathways in ways previously unattainable by Western blotting," said Brad Calvin, vice president of Beckman Coulter's Flow Cytometry Business Center.  "The combined whole-blood application, which incorporates robust cell preparation and high affinity antibodies, creates the potential to transform our understanding of cell signaling’s role in disease, while also providing the pharmaceutical industry with the potential for improved characterization of target compound function and effect."

Step up to the MIQE

Mar 30

Over the years, polymerase chain reaction (PCR) has evolved into a readily automated, high throughput quantitative technology. Real-time quantitative PCR (qPCR) has become the industry standard for the detection and quantification of nucleic acids for multiple application, including quantification of RNA levels. But a lack of consensus among researchers on how to best perform and interpret qPCR experiments presents a major hurdle for advancement of the technology. This problem is exacerbated by insufficient experimental detail in published work, which impedes the ability of others to accurately evaluate or replicate reported results.

Fast Optimization of a Multiplex Influenza Identification Panel Using a Thermal Gradient

Mar 30

The year 2009 was marked by the emergence of a novel influenza A (H1N1) virus that infects humans. There is a need to identify the different strains of influenza virus for purposes of monitoring the H1N1 strain pandemic and for other epidemiological and scientific purposes.

Advantages of Monolithic Laser Combiner Technology in Confocal Microscopy Systems

Jan 6

Fluorescence microscopy techniques require a reliable light source at the desired wavelength or wavelengths, with minimal downtime for maintenance and alignment. Lasers are a popular light source, although the alignment and upkeep of laser combiners is a time-consuming prospect for many users.

Size-Exclusion Chromatography for Purification of Biomolecules

The poster describe the process involved in automating a Cytometric Bead Array (CBA) immunoassay developed to measure relative concentrations of serum antibodies against Tetanus (TT), Sperm Whale Myoglobin (SWM) and Keyhole Limpet Hemocyanin (KLH) in KLH-immunized volunteers.

Ensuring Quality in Assays Performed with Automated Liquid Handlers

Feb 2

The focus of this presentation is to highlight the need of ensuring quality in important assays performed with automated liquid handlers. Nearly all assays performed within a laboratory are volume-dependent. In turn, all concentrations of biological and chemical components in these assays, as well as the associated dilution protocols, are volume-dependent. Because analyte concentration is volume-dependent, an assay’s results might be falsely interpreted if liquid handler variability and inaccuracies are unknown or if the system(s) go unchecked for a long period.

Inkjet System for Protein Crystallography

Feb 1

X-ray crystallography is used routinely by scientists to obtain the three dimensional structure of a biological molecule of interest.Such information can be used to determine how a pharmaceutical interacts with a protein target and what changes might improve functionality. However, the crystallization of macromolecules still remains a serious hindrance in structural determination despite impressive advances in screening methods and technologies.

Attention Deficit & Hyperactivity in a Drosophila Memory Mutant

Attention Deficit & Hyperactivity in a Drosophila Memory Mutant

Nov 9 2009

Action selection is modulated by external stimuli either directly or via memory retrieval. In a constantly changing environment, animals have evolved attention-like processes to effectively filter the incoming sensory stream. These attention-like processes, in turn, are modulated by memory. The neurobiological nature of how attention, action selection and memory are inter-connected is unknown. We describe here new phenotypes of the memory mutant radish in the fruit fly Drosophila.
