  • 3D cell imaging made easier

    Tue, 29 Jan 2019 18:00:00 GMTBy: (Bindi M. Doshi, PhD)

    There is an increase in demand for scientists to show cell migration and proliferation on a surface that more closely mimics an in vivo environment.  Using a gel surface can be tricky.  Therefore, MBL has a unique and innovative technology where a proprietary plastic film is used for plating cells.  This technology is easy to use with many different cell types and is reproducible every time.  Please see the table below comparing various techniques for 3D cell cultures: Read more
  • LC3: The gold standard for autophagy research

    Thu, 13 Dec 2018 18:00:00 GMTBy:

    LC3, a mammalian homologue of yeast ATG8, is a soluble protein that is distributed ubiquitously in mammalian tissues and cultured cells. LC3 has been studied most extensively and is frequently used as an autophagy marker in mammals.  Newly translated LC3 (proLC3) is immediately processed at the C-terminus in order to form LC3-I. During autophagy, autophagosomes engulf cytoplasmic components, including cytosolic proteins and organelles. Concomitantly, a cytosolic form of LC3 (LC3-I) is conjugated to phosphatidylethanolamine to form LC3-phosphatidylethanolamine conjugate (LC3-II), which is recruited to autophagosomal membranes.

  • Gating strategy for tetramer analysis to eliminate non-specific event

    Wed, 14 Nov 2018 18:00:00 GMTBy:

    While MHC tetramer staining of antigen specific T cells for flow cytometry is considered highly specific, it could still be associated with non-specific staining. The gating strategy shown below is an example that investigators have used to reduce non-specific staining events using a dump channel. A dump channel can be planned on a case by case basis, on the experimental design, and consists of a pool of antibodies against cells that do not express our specific targets. For example, CD8+ T cells, anti-CD4/anti-CD14/anti-CD19 may be used to eliminate these immune cells from our targeted gate, and all may be labeled with the same fluorochrome.  Read more
