Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.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.

Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.DNA / RNA Extraction and PurificationPurified DNA and RNA are required for numerous downstream molecular biology applications. Consequently, the importance of high-quality DNA/RNA extraction and purification equipment cannot be underestimated. Many purification kits are available and are typically optimized for nucleic acid type and source, including plasmid DNA, genomic DNA, mRNA, RNA and viral nucleic acid purification kits. Automated extraction and purification of nucleic acids can be implemented with magnetic bead separator instruments or high-throughput purification workstations.

The purification process typically involves subcellular or membrane protein extraction with cell lysis kits, separation of proteins from cell debris by filtration or spin columns, and the isolation of proteins of interest from other proteins and impurities with affinity purification (including fusion protein tags and antibody binding proteins A, G and L), immunoprecipitation or chromatographic methods, such as ion exchange, size exclusion and immobilized metal affinity chromatography. All purification methods come in multiple formats for your laboratory needs, including agarose or magnetic beads, resins, columns and filter plates.

RNAi requires chemical synthesis, introduction of DNA vectors into cells, an assay of RNAi effects and RNAi quantification or analysis. Consider target sequence selection, reagent preparation, controls, high specificity and effectiveness and low non-specific gene knockdown.Nucleic Acid ConcentrationQuality ControlQuality control is needed in all production processes. Quality control is a monitoring procedure or set of procedures that are put in place to ensure that a manufactured product adheres to a defined set of quality criteria. Protein BiologyThe analysis of protein expression, identity and function is vital for many areas of life science research and drug discovery. Some of the most commonly used techniques in protein analysis include Western blotting, electrophoresis and mass spectrometry.DNADeoxyribonucleic Acid (DNA) is the main component of chromosomes and the carrier of genetic information of living organisms. Find out here about PCR, NGS, ChIP-Seq, gel imaging, and many other techniques which can be used for the analysis of DNA.Quality TestingQuality testing ensures that products meet required specifications and safety standards in various industries, including pharmaceuticals, food, and materials.
