6640--646-21-3-1410-0752 Cytek Aurora (VA-21-00063331)

The VA Pittsburgh Healthcare System Research department has a need for a spectral analyzer system to support current research activities, Brand Name or equal to the Cytek Auroa 5 and components described below.

Cytek Aurora 5 or equivalent. System consists of:

Cytek Aurora 5 Laser US/V/B/YG/R (64+3 Channel)

5-laser flow cytometer

Workstation w/computer, monitor, keyboard, and mouse

Intel Core i7, 3.6 GHz

64-bit

32 GB RAM

500 GB Hard Drive

530 NVIDIA GeForce Video Card

32-in UHD 4K Monitor

Microsoft Windows 10 Pro

Additional copy of SpectroFloTM

Fluidic reservoirs

QC and consumable parts kit

1-year warranty

Cytek Auto Micro-Sampling System

Salient Characteristics

Five lasers: Violet, Blue, Yellow-Green Red, Ultraviolet.

3 scattering channels

Up to 40 colors detected

64 fluorescence channels

Capable of detecting up to 30 fluorochromes using spectral analysis.

96-well sampling capability

Autofluorescence extraction

High-sensitivity Coarse Wavelength Division Multiplexing (CWDM), 16-channel semiconductor detector

Flat top beam profiles

Full emission spectra

Highly overlapping dyes

Multiparametric data

100 mW 405 nm laser

SSC detector

System must be able to:

Detect up to 40 colors including fluorochromes with overlapping emission spectra.

Immune cell subsets identified by single cell RNA seq need to be validated by VA researchers for protein expression. System must be able to detect up to 100 rare immune cell subsets

The equipment must have high sensitivity, which is optimal to analyze the most challenging cell populations such as cells with high autofluorescence or low levels of expression of biomarkers. The machine must not require changing optical filters for any fluorochromes, and any commercially available fluorochromes must be be excited by the system.

Full spectrum unmixing for detection of fluorescent signals. No band pass filters or photomultiplier tubes (PMTs)

Cytometer must have flat top laser beam profile with narrow vertical beam height for enhanced capacity to detect rare events and particles smaller than cells

Ability to use violet laser line for cell or particle scatter measurements.

Operating voltage can be 100 or 240 V

No special environmental requirements (air, humidity, and temperature)
