The mixture contains 15 double stranded DNA fragments with the following base pair lengths: 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500 and an additional band of 2642 bp. The 500 bp and 1000 bp banding pattern is two to three times brighter. Application The DNA Molecular Weight Marker XIV allows accurate sizing of DNA fragments generated by PCR or restriction digest separated on agarose gels. The DNA molecular weight marker can be used in conjunction with DNA Molecular Weight Marker XIII (50 bp ladder)* for precise size determination. Electrophoretic separation of this molecular weight marker results in a regular pattern. The fragments have 5'-protruding ends which can be labeled by filling in reactions using e.g. [32P]-dTTP and [32P]-dGTP, or using DIG-11-ddUTP* and Terminal Transferase*. Typical analysis The DNA fragment mixture shows the ladder with 15 bands and an additional band of 2642 bp in agarose gel electrophoresis as shown in the figure.

Agarose Gel Electrophoresis
Laboratory for Environmental Pathogen Research Department of Environmental Sciences University of Toledo Agarose gel electrophoresis Background information Agarose gel electrophoresis of DNA is used to determine the presence and distinguish the type of nucleic acids obtained after extraction and to analyze restriction digestion products. Desired DNA fragments can be physically isolated for various purposes such as sequencing, probe preparation, or for cloning fragments into other vectors. Both agarose and polyacrylamide gels are used for DNA analysis. Agarose gels are usually run to size larger fragments (greater than 200 bp) and polyacrylamide gels are run to size fragments less than 200 bp. Typically agarose gels are used for most purposes and polyacrylamide gels are used when small fragments, such as digests of 16S rRNA genes, are being distinguished. There are also specialty agaroses made by FMC (e.g., Metaphor) for separating small fragments. Regular agarose gels may range in concentration from 0.6 to 3.0%. Pouring gels at less or greater than these percentages presents handling problems (e.g., 0.4% agarose for genomic DNA partial digests requires a layer of supporting 0.8% gel). For normal samples make agarose gels at 0.7%. The chart below illustrates the optimal concentrations for fragment size separation. The values listed are approximate and can vary depending on the reference that is used. If you do not know your fragment sizes then the best approach is to start with a 0.7% gel and change subsequently if the desired separation is not achieved. Nucleic acids must be stained prior to visualization. Most laboratories use ethidium bromide but other stains (e.g., SYBR green, GelStar) are available.

Agarose Gels (Horizontal Gel Electrophoresis)
TECHNIQUES IN MOLECULAR BIOLOGY – AGAROSE GELS (HORIZONTAL GEL ELECTROPHORESIS) DNA gels are used to separate fragments of DNA and RNA. Unlike most protein separations which use acrylamide polymers, use agarose in a submerged horizontal orientation, and at time called horizontal gel electrophoresis. This handout will cover the details of agarose gels, the theory of separation by agarose gel electrophoresis and tips for conducting successful gel electrophoresis. The basic principle of separation for all electrophoresis is the movement of a charged molecule in a medium subjected to an electric field. v=Eq/f V is the velocity of the molecule subjected to electrophoresis. E is the electrical field in volts/cm, q is the net charge on the molecule and f is the frictional coefficient. The impact of f depends on the mass and shape of the molecule. This equation simply explains that the rate (v) of a particle depends on the electrical field and charge but inversely impacted by the counteracting force generated by the viscous drag. Factors influencing F is of course the size and shape of the molecule. Think of a short linear oligonucleotide vs a large supercoiled plasmid vs long chromosomal DNA. Adding a value to f is the media through which the molecules migrate. Agarose is a seaweed extract (red algae agar) and is a long polymer of D and L galactose and derivatives in a linear polymer bonded by two different glycosidic bonds. Once hydrated and formed into a gel, the carbohydrate will form helical Repeating pattern of agarose fibers and aggregates creating channels of 50 to more than 200 nm in diameter.

GENERAL BIOLOGY LABORATORY II Bioassays of Major Biomolecules: Nucleic Acids
Weeks 9-10: Bioassays of major biomolecules: Nucleic acids GENERAL BIOLOGY LABORATORY II Canbolat Gürses, Hongling Yuan, Samet Kocabay, Hikmet Geckil Department of Molecular Biology and Genetics Inonu University Weeks 9-10 Bioassays of major biomolecules: Nucleic acids DNA is the genetic material in all organisms. Scientists work with DNA for a variety of reasons, such as cloning, amplification, sequencing, and other genetic manipulations. In general, the first steps in DNA (or RNA) studies involve DNA isolation and their qualitative, and quantitative determination. DNA or RNA concentration in solution can be determined through the optic properties (max. absorbance) of nucleotides at 260 nm. Once their concentration and purity are determined, nucleic acids can be investigated with more specific and sensitive methods (e.g., agarose gel electrophoresis, etc.). 1 DNA can be extracted and isolated from any cell, tissue, or organ using a variety of methods such as alkali lysis, enzymatic lysis and boiling methods and it can be precipitated from the rest of cell components by ethanol, isopropanol precipitation. As we have seen for proteins which have specific absorbance maxima at 280 nm, nucleic acids absorb light maximally at 260 nm. However, while one unit A at 280 nm is equal to one unit of protein (as mg ml-1), for DNA and RNA 1 A unit at 260 nm is equal to about 50 and 40 µg ml-1, respectively. The cell extract is a mixture of all cell components and organelles. Once large particles (e.g., organelles, membrane fragments, etc) are removed by a low speed centrifugation, the solution part (i.e., supernatant) contains cell components such as proteins and nucleic acids dissolved in an aqueous environment.

Design and Fabrication of Low-Cost Microfluidic Channel for Biomedical Application
www.nature.com/scientificreports OPEN Design and Fabrication of Low-cost Microfuidic Channel for Biomedical Application Shailendra Kumar Tiwari1, Somashekara Bhat1 ✉ & Krishna K. Mahato2 This paper presents the design, simulation and low-cost fabrication of microfuidic channel for biomedical application. Channel is fabricated using soft lithography technique. Printed Circuit Board (PCB) is used to make the master for the channel. Channel pattern is transferred on PCB plate using toner transfer technique followed by ferric chloride etching. Paper also discusses, the issues involved in PCB based master fabrication and their viable solutions. Glass is used as substrate material and the channel is made of Sylgard 184 Polydimethylsiloxane (PDMS). Channel is interfaced with a syringe pump to observe the fuid fow. To predict the behavior of the channel, FEM simulation is performed using COMSOL Multiphysics 5.2a. There is a good match between the theoretical, simulation and test results. Finally, to test the biocompatibility of the channel, genomic DNA is passed through the channel and gel electrophoresis analysis is performed. Microfuidics deals with the study of devices that can handle the very small amount of liquid down to femtoliter with the help of small channels and reservoirs. Te dimensions of microfuidic devices range from ten to hun- dreds of micrometers1–5. Tese devices have promising applications in biological analysis6–9 chemical analysis10, optical communication11, cooling of Integrated Circuits (ICs)12, and many more. In microfuidics, scaling down the device dimensions to microscale reduces the amount of sample and reagents required to perform the assay, resulting in a huge saving in cost and the reduction in the amount of waste produced.
