George McNamara

Light Microscopy Reflection Focusing Cells and Coverglass 20150520Wed

Many light microscopes have the capability of using camera based brightfield, phase contrast, or fluorescence to find the most contrasty specimen focus. When I worked for UIC (1992-1997) we offered this with a combination of Ludl MAC2000 controller, Z-drive, video card thingy, and video camera (most customers at the time used analog video cameras).

Many automated light microscopes now have clever -- and pricey -- autofocus systems based on an NIR LED structured illumination reflecting light off the bottom of the coverglass.

I encourage a simpler approach - my hardware details are in the text ...

Tattletales and T-Bow Update 20141018

http://0-works.bepress.com.library.simmons.edu/gmcnamara/63

Tattletales is my concept to multiplex fluorescent protein biosensors ("Tattletales", which is also the overall concept name) and multicolor FP reporters ("T-Bow" for Rainbow T-cells and tumor cells) to study the physiology of live cells.

These are based on:

1. LacI-GFP :: LacO operator synthetic tandem repeat array (Robinett et al 1996 JCB, Fig 4A, http://jcb.rupress.org/content/135/6/1685.full.pdf )

2. the plethora of fluorescent protein biosensors - see page 1 of this "63" download site.

Rather than trying to compute the average of (say) a triangle and a pentagon ... which might result in a square, or a rectange, or some bizarre quadrilateral ... R.M. advocated using the median. OK, in a 2 member dataset this would result in averaging the two shapes (if use ...

Tattletales for Multiplex Fluorescent Reporters in Single Cells for Metabolomics

George McNamara

As of April 2013: L.J.N. Cooper & D.A. Lee Cellular Immunotherapy Lab, University of Texas M.D. Anderson Cancer Center, Houston, TX

Email: gtmcnamara@mdanderson.org, geomcnamara@earthlink.net

Tattletales is my concept for spatial multiplexing many fluorescent protein (FP) biosensors in the same live cell. For example, there are excellent FP biosensors to Ca++ ions, pH, glucose, ribose, glutamine, glutamate, ATP, redox, ROS, pyruvate, cAMP, cGMP, IP3, PI(3,4,5)P3, cell cycle indicators (Fucci2), PKA, PKC, photsphatases, caspase(s) [1, 2]. However, these are typically used one biosensor per experiment, due in part to flooding the cell with soluble biosensor. That is, conventionally, either a metabolite (glucose) reporter or a signal transduction (Ca++) reporter can be imaged. By flooding the cell with the reporter, signal to noise ratio is compromized by autofluorescence.

Tattletales takes advantage of spatial multiplexing to both increase the number of different reporters, and improve signal to noise ratio by localizing each biosensor to a small volume. I started with the observation by Robinett et al [3] who localized 512 GFP-nls-LacI to a 256 LacO array as a 200 nm diameter diffraction limited spot (nuclear background due to overexpression). Many thousands of DNA binding proteins, of known sequence specifities, exist (LacI, TetR, GalR, etc for cell line studies; ZF-FPs, TALE-FPs to STRs, telomere repeat binding factors-FPs, etc for primary cells) and can be fused (as cDNAs) to different fluorescent proteins and FP biosensors.

Many biosensors are available as affinity series [1, 4], now enabling extended dynamic range. I realized that spatial multiplexing of many DNA binding protein-reporters by localizing to different spots in the cell nucleus and distinguished by combinatorial addressing, where N address colors provide 2^N addresses (example, 3 colors is 2^3 = 8 combinations). Multiplexing ...

Cosmic ray particles image series acquired using a Hamamatsu ORCA-II ERG scientific grade CCD camera, cooled to -60 C. Each image is a consecutive 600 second (10 minute) exposure time with no light to the camera.

The Internet is enabling greater access to spectral imaging publications, spectral graphs, and data than that was available a generation ago. The spectral imaging systems discussed in this issue of Cytometry work because reagent and hardware spectra are reproducible, reusable, and provide input to spectral unmixing and spectral components recognition algorithms. These spectra need to be readily available in order to determine what to purchase, how to use it, and what the output means. We refer to several commercially sponsored and academic spectral web sites and discuss our spectral graphing and data sites. Sites include fluorescent dye graph servers from ...
