Live-cell imaging technique allows
real-time examination of almost every aspect of cellular function under normal
and experimental conditions, so it is especially popular with cytology
researchers. Abbkine TraKine™ Pro is a series of cell-permeable organic fluorescent
probes which can selectively recognize and label organelles. Currently, we
launched the staining kits involve tubulin, lysosome, mitochondrion and nuclei.
This paper introduces the TraKine™ Pro Live-cell Nuclei Staining kit (Deep Red
Fluorescence with Super Resolution).
Function of nucleus
The nucleus is the largest and most important cell structure in eukaryotic cells, mainly composed of nuclear envelope, chromatin, nuclear skeleton, nucleolus and nucleosome. Nuclear membrane is a two-layer membrane that completely encloses the nucleus and separates the material within the membrane from the cytoplasm and lamina.
The nucleus contains most of the cell’s
genome, organized as multiple long linear DNA molecules in a complex with a
large variety of proteins, such as histones, to form chromosomes. It is the
regulatory center of cell heredity and metabolism, and plays an important role
in cell metabolism, growth and differentiation.
Commercially available nucleus fluorescent probes
The
nucleus is the place where the genetic material is stored and reproduced, and
it is also the control center of cellular heredity and cell metabolism. Studying
its function, mechanism, dynamics and interaction is important direction for
cytology researchers.
At
present, the existing nuclear dyes (such as PI, DAPI, ethd-1, etc.) are mostly
used for dying cell staining, apoptosis research, nuclear counterstaining, and
so on. Hoechst dye is a compound synthesized by Hoechst AG originally, which is
soluble in water and organic solvents. It can cross cell membranes and bind to
living or fixed cells, the fluorescence intensity enhanced along with the increase
of the pH value of the solution.
Product name | Cat# | Ex/Em（nm） | Application |
DAPI | BMD00063 | 358/461 (with DNA) | Dead cell staining; counterstaining; Apoptosis study |
Hoechst 33258 | BMD00061 | 352/461 (with DNA) | Live or fixed cells; Apoptosis study |
Hoechst 33342 | BMD00062 | 350/461 (with DNA) | Live cells or tissues; fixed cells or tissue; Apoptosis study |
Ethidium Homodimer-1 (EthD-1) | BMD00060 | 528/617 (with DNA) | Dead cell staining; High affinity fluorescent nucleic acid dyes, binding DNA or RNA |
However,
there is no dye that can be used to observe the dynamics of living cell nucleus
very well currently. Abbkine researchers developed a unique TraKine™ Pro
fluorescent probe that can track the 3d dynamics of living cell nucleus for a
long time with ultra-high resolution.
The TraKine™ Pro nuclear fluorescence probe has been
specially optimized, which contains a fluorescent dye and a small molecular
group that specifically identifies the nucleus, to locate the nucleus and track
its dynamics and changes. It is the only highly specific live cell nuclear
staining product on the market.
