DRAQfx™ in Immunofluorescence
19 Jan 2018Immunofluorescence (IF) microscopy often involves the analysis of adherent cells or tissue sections where samples have been preserved with formaldehyde-/formalin-fixation (FF). Tissue samples can be paraffin– embedded (FFPE) or snap-frozen. After sectioning they are processed to enable analysis, which might include dewaxing, rehydration, antigen retrieval and permeabilized with weak surfactant to make cells permeable to antibodies. Then, fluorescently-tagged antibodies can be used to label internal structures in adhered cells or thin tissue sections. It is important to view any antibody staining of cells in the context of an individual cell and its internal structure as well as any adjacent tissue morphology.

UV-Visible SpectroscopyUltraviolet-visible (UV-Vis) spectrophotometers are used to measure the interaction of UV and visible light with a sample, including transmission, reflectance & absorbance. The two major instrument classes are single-beam or double-beam spectrophotometers. More specialized equipment includes colorimeters, spectroradiometers and refractometers. Portable and microvolume spectrophotometers are also available. For the modular spectroscopy lab, explore a range of light sources for combination with a spectrograph/spectrometer and optics.

Microorganisms are a useful research tool as genetic vectors and, in immunology, for antibiotic susceptibility testing, cellular biology and genetics. Microorganisms commonly grow readily in incubators with microbial culture media; this can contain chromogenic supplements to differentiate between cell lines. Estimate your culture’s density of microorganisms with colony counters, or screen and select colonies for desirable clones with automated colony pickers. Additionally, equipment is available to monitor environments for the presence of microbes and identify with microbial identification instruments.

Immunology kits and analysis systems often use techniques such as ELISA, radioimmunoassay (RIA) and immunodiffusion assays, Immunohistochemistry, and flow cytometry. Immunologists use equipment such as flow Cytometers, plate readers, plate washers and fluorescent microscopes.ImmunofluorescenceCell BiologyCell biology studies the structure, function, and behavior of cells. Understanding cellular processes is essential for research in areas such as cancer biology, stem cell research, and neurobiology. Techniques like flow cytometry, microscopy, and cell culture enable researchers to explore cellular mechanisms in detail.
