Facility In Charge: Siddhi A. Redkar

The Electron Microscope Facility at ACTREC is equipped with JEM 1400 PLUS, a Transmission electron microscope (JEOL, Japan) functioning at 120kV with magnification up to 12,00,000 X and 0.2nm resolution. TEM analysis provides a detail ultra- structural information of resin embedded or negatively stained biological samples. The facility extends its services for research and analysis of biological samples, nanoparticles and other applications to the external researchers along with the in-house researchers. The facility is also equipped with instruments such as ultra-microtome, glass knife-maker, auto-trimmer and glow discharge unit.

Current Applications
  • The facility carries out sample preparation for routine electron microscopy, including resin block making (solid tissues, monolayer cell cultures, and cell suspensions) followed by ultrathin sectioning using Leica UC-7 ultramicrotome, contrasting, and acquisition.
  • The facility also carries out negative staining for small particles (<100nm) like bacteriophages, exosomes, nanoparticles, proteins and DNA.
  • The facility provides acquisition of immunogold labelled macromolecules to detect specific localization.
  • The facility provides elemental detection by Bruker EDS system

The major areas of electron microscopy analysis are,

  • Ultrastructure study of cell and tissue,
  • Studying the details at organelle level like mitochondrial changes, ER - mitochondrial interactions, mitochondrial cristae, cell membrane, nuclear architecture, golgi complexes etc.,
  • To check events of autophagy, apoptosis or necroptosis,
  • Characterization of exosomes, bacteriophages and nanoparticles,
  • Uptake and effect of nanoparticles / drugs / radiation on cells or tissue,
  • EDS analysis of nanoparticles
Sample Submission

External users: Please write to the facility regarding your requirement for electron microscopy. The facility will provide the details as per the analysis requirement. The users are requested to discuss over email regarding their study and sample submission followed by booking a slot accordingly. The samples need to be submitted along with a duly filled requisition form. For quotation, a duly filled requisition form can be mailed to the facility email address (tem.facility@actrec.gov.in). For requisition form, please click the link below,

Internal users (ACTREC):

  • For routine EM, please check with the facility regarding the sample submission requirements as per the study.
  • For negative staining, please book a slot after discussing with the facility for sample submission. Only three samples will be accepted per slot.

    • Samples should be accompanied by a duly filled requisition form and online requisition.
