Usually caused by sporadic 17p11.2 deletion encompassing the retinoic acid-induced 1 (RAI1) gene or a mutation of RAI1, Smith-Magenis syndrome generally involves variable mental retardation, sleep disturbance, craniofacial and facial abnormalities, developmental delay, and behavioral problems. Here we present a brief introduction to the common knowledge of Smith-Magenis syndrome.

  • DNA Extraction by Phenol/Chloroform

    This method relies on phase separation by centrifugation of a mix of the aqueous sample and a solution containing phenol and chloroform, resulting in an upper aqueous phase and a lower organic phase (mainly chloroform). DNA is present in the aqueous phase and can be recovered by precipitation with isopropanol or ethanol.

  • FastLink HRP Labeling Kit

    The FastLink HRP Labeling Kit allows conjugations to set up in seconds, simply by adding a solution of the protein to be labeled to a proprietary lyophilised HRP mixture. By circumventing the desalting or dialysis steps that commonly interrupt traditional protein conjugation procedures, FastLink technology can be used to label small quantities of protein with 100% recovery and no excessive dilution of the conjugate. This video shows you how to set up conjugation reactions.

  • mRNA Extraction

    Due to the low proportion of mRNA (only 1~5% of the total RNA), reducing the amount of rRNA and tRNA in a total RNA preparation increases the relative amount of mRNA. mRNA enrichment is essential for construction of cDNA libraries and other applications where intact mRNA is highly desirable. This video shows how to use affinity resin to isolate mRNA.

  • Gel Extraction

    Gel extraction is a technique used to isolate a desired fragment of intact DNA from an agarose gel following agarose gel electrophoresis. Three basic steps are involved: slicing the bands of interest on UV light exposure, isolating the DNA from those bands, and removing the accompanying salts and stain.

  • 2D Gel Electrophoresis (12) Mass Analysis

    Two-dimensional gel electrophoresis, (2-DE or 2D electrophoresis), is a form of gel electrophoresis commonly used to isolate the proteins in a sample for further characterization by mass spectroscopy. Mixtures of proteins are separated in the 1st dimension by their charge (isoelectric focusing (IEF)). Then in the 2nd dimension, proteins are separated by their size (molecular weight). This video shows the part 12- mass analysis.

  • Micropipette Calibration

    Micropipettes are used to accurately measure and dispense small volumes of liquid. The capacity of a micropipette can range from less than 1μl to 1000μl (1ml). To ensure that obtained results using micropipette are reliable, it is necessary to calibrate micropipettes several times a year. This video shows a method for testing the accuracy of automatic micropipettes.

  • Optical Fiber Cleavage

    Optical fibers are flexible, transparent fibers made of high quality extruded glass (silica) or plastic. It is frequently adopted as a waveguide, or "light pipe", to transmit the optical signals. Taking advantages of this kind of property, optical fibers have been used in developing biological sensors in concert with traditional bio-probes such as nucleic acids. Here weve demonstrated the operation of automated fiber cleavage to produce flat and angled cleaves on fibers ranging from 80 microns to 1.25 mm in diameter for following biological applications.
