Muscle Immunohistochemistry and Molecular Imaging Core (MIMIC)

The Muscle Immunohistochemistry and Molecular Imaging Core (MIMIC) offers several services to researchers working with muscle, including sectioning of frozen muscle tissue, histological and  immunohistochemical muscle characterization and imaging of common muscle features. MIMIC provides access to automated image analyses software MyoVision Basic for download, and provides high throughput image quantification services MyoVision Pro. MIMIC also provides access to human vastus lateralis tissue sections (see Human Muscle Resources). Additionally, we are glad to offer insight and expertise related to muscle characterization and established histological/immunohistochemical protocols. 

For information about the services we offer, please visit our Rates page. To request a service, please submit a Service Request Form. We are proud to support basic, clinical and translation research aimed at  understanding the mechanisms underlying the regulation of muscle structure and function and the impact on physical activity and chronic disease. If you have any questions or special requests, please contact us.

 

 

Equipment

  • MICROM HM525 Cryostat – user friendly, this cryostat can be set for temperatures between +5 and -35°C. Sections can be cut at thicknesses ranging from 1-500 μm. Completely motorized stage head automatically retracts and repositions for optimal sectioning. LED displays allows for tracking of wheel rotations or length of travel making it easier to track tissue mount usage. Equipped with Peltier element for rapid freezing of specimens.
  • MICROM HM525NX Cryostat – the newer version of the HM525, this updated cryostat has completely digital, touchscreen controls allowing for more fine tuning of section thickness. Like the HM525, the 525NX has a cryobar equipped with a Peltier element which can cool to -60°C, used for rapid freezing of specimens.
  • Zeiss AxioImager M1 Upright Fluorescent Microscope – with a semi-automated stage and filter wheel, the AxioImager can acquire whole section images (stitched). This scope is equipped with four fluorescent filters (DAPI, FITC, TRITC and Cy5) and 4 air objectives (5x, 10x, 20x and 40x) plus a 100x oil objective. Fluorescence is illuminated with an X-cite 120 lamp and liquid light guide. The color camera (AxioCam ICc5) acquires high resolution bright field images (5 megapixels), while fluorescence images are acquired with a high sensitivity black and white camera (AxioCam MRm). Image capture is done using Zen blue software from Zeiss.
  • Zeiss AxioObserver D1 Inverted Fluorescent Microscope – the AxioObserver D1 is a fully manual scope outfitted with a color (AxioCam MR) and a black and white (AxioCam MRm) camera. Fluorescence is illuminated with an X-cite 120 lamp and liquid light guide. There are four available filters on this microscope: DAPI, FITC, Piston GFP (narrow band helps minimize autofluorescence) and TRITC. Available objectives include: 4x, 10x, 32x, 40x and 125x. Images are acquired with Axiovision software.
  • Olympus BX61VS Upright Fluorescent Microscope – the Olympus BX61VS has a fully automated stage which can hold up to 5 slides at once. This microscope is great for imaging large batches of slides and can capture entire tissue sections and even entire slides. 2x, 10x, 20x and 40x air objectives are available for capture of overview images or high magnification mosaic images. The BX61VS is equipped with both a color (Pike F505, 5 megapixel) and a black and white (Olympus XM10) camera for bright field or fluorescent imaging. Four fluorescent filters are available for multichannel imagining (DAPI, FITC, TRITC and Cy5) and fluorescence is illuminated with an X-cite 120 lamp and liquid light guide. Images are acquired with VSI software. 
  • Independent Workstations with fully licensed versions of Zen blue – in addition to image capture, we have 3 independent workstations with fully licensed versions of Zen. These workstations can be scheduled for more complex analysis following image capture. One workstation includes a Microsoft Perceptive Pixel, 55” touch monitor, useful when outlining specific structures is necessary. 

Equipment can be scheduled using our Sharepoint calendar (link provided following completion of training).

  • ZEN Lite - ZEN lite allows you to open, view, change display, export image files acquired with Zen blue (.CZI). It also has some measurement and analysis features.
  • OlyVIA - OlyVIA allows you to open and view image files acquired with the Olympus BX61VS microscope (.VSI).
  • Image J - This is free software provided by the NIH. Image J has several plug-ins that can open various file types for viewing, saving or analysis.
  • Spectr Views/Analyzers - If you are unsure of which fluorophores to pair together, these viewers can help you make the best choice by showing you the excitation and emission spectra for multiple fluorophores within one display.
