Do you use pre-packed Superdex 75 or Superdex 200 columns for gel filtration chromatography? Ever wonder if other media could better address your purification needs? Look no further. Your quest ends here! But if you’re looking for information on gel filtration principles, check out this earlier article. Choosing a Column for your Gel Filtration Experiment…
CIP has been around for a while, but there is a better alternative.
One of the much sought after question asked by many researchers worldwide is – “What is the gene expression profile of a single cell within a heterogenous pool of cells?” While mass cytometry is the current ‘hot’ methodology for single cell analysis, the good old flow cytometry can help us perform rapid analysis of single…
Flow cytometry remains unparalleled as a single-cell analysis technology. The ability to analyze 14 or more fluorescent parameters on a million cells or more allows for detailed understanding of complex biological processes. The Problem With Traditional Flow Cytometry One limitation of flow cytometry is the reliance on fluorescent tags. Even with careful panel design, loss…
What is one of the first things you do when you sit down at the flow cytometer and start looking at your cells? You start drawing polygons and setting gates. To the neophyte the gating process can look a little random – why do you exclude those dots but not these? But gating in flow…
One of the key characteristics of cytotoxic cells (i.e. CD8+ T cells, natural killer cells) is the presence of pre-formed cytoplasmic lysosomal granules. These structures house perforin and granzyme; two molecules that are essential for the lysis of target cells. Upon effector cell activation, granules are polarized toward the target cell and the contents are…
