FACSAria™III- Fluorescence Assisted Cell Sorter (FACS)

  • Separates or sorts cells that are phenotypically different from each other, as well as, cells that express proteins of interest.
  • High-speed fixed alignment laser bench top sorter that has the ability to sort or isolate cells of interest from a mixed population of cells. 
  • Equipped with 405 nm, 488 nm, 561 nm, 631 nm lasers and is capable of up to 10 color simultaneous detection
  • Subpopulations of cells are tagged with a fluorescent-conjugated antibody that binds to a protein uniquely expressed by the cells of interest.
  • Multiple sorting options, from sorting single population of cells, up to sorting four different cell populations in a temperature-controlled environment.
  • Single cells may also be sorted directly onto standard cell culture plates. 
  • Sorting, data acquisition, and analysis are controlled by BD FACSDiva software.

AVIV Stopped-Flow Circular Dichroism 202SF Spectrometer

  • Exploits the chiral nature of biological molecules and difference in their interaction with right and left circularly polarized light.
  • Records circular dichroism spectrum as a function of wavelength, pH, time, temperature and concentration.
  • Provides excellent quality scans in the far UV range of 195-240 nm at a temperature ranging from 5 °C and 95 °C wavelength, enabling quantitative secondary structure analysis.
  • Capable of evaluating protein folding events on timescales of 5 ms or longer with the stopped-flow mixing module.
  • Use 450W Xenon arc lamp with a synthetic fused silica envelope as light source.

LightCycler® 480 Real-Time PCR System

  • A novel high-throughput, plate-based, thermal block cycler with integrated real-time, online detection capabilities.
  • Provides remarkable well-to-well temperature homogeneity and maximized inter-well, inter-cycle reproducibility.
  • Provides the ideal solution for fast and precise qualitative or quantitative detection of genotyping, mutation scanning, and nucleic acids.
  • Allows the use of all current probe formats (e.g.,SYBR Green I, hydrolysis probes, HybProbe probes, SimpleProbe probes).

ABI 433A Peptide Synthesizer

  • Fully automated, programmable instrument that performs the chain assembly steps in solid-phase peptide synthesis (SPPS)
  • Performs Fmoc Chemistry to carry out SPPS where FastMoc kit (Applied Biosystems). containing HBTU is the activation reagent in the presence of NMP.
  • Monitor the synthesis by real-time, feedback monitoring feature based on the measurement of conductance by a built in conductivity cell.

Optima XLI Analytical Ultracentrifuge

  • A state of the art instrument to determine molecular masses, stoichiometry of oligomerizations, binding constants for associating systems and sample homogeneity through sedimentation velocity and sedimentation equilibrium analyses.
  • Equipped with sensitive absorbance optics as well as interference optics for sample detection, both detection methods can be simultaneously utilized, if needed.

Real-Time Imaging Microscopy

  • Real-time imaging of live cells.
  • Time-lapse imaging.
  • Imaging of bright field or fluorescently labeled cells.
  • Calcium imaging.
  • Environmentally controlled chamber.
  • Nikon Elements software is used to acquire and process the acquired data. (
