	SDS-PAGE - Wikipedia, the free encyclopedia
		The denatured proteins are subsequently applied to one end of a layer of polyacrylamide gel submerged in a suitable buffer.
		Gel electrophoresis is usually the first choice as an assay of protein purity due to its reliability and ease.
		During electrophoresis in a discontinuous gel system, an ion gradient is formed in the early stage of electrophoresis that causes all of the proteins to focus into a single sharp band.

	[No title]
		When subjected to polyacrylamide gel electrophoresis, the proteins are separated according to size by the molecular sieving effects of the gel.
		Polyacrylamide gels are generated by the polymerization of acrylamide monomer and the crosslinking co-monomer N,N'-methylene-bis-acrylamide (referred to as bis).
		The gel is run at 150 volts (constant voltage) for 1 hour or until the bromophenol blue dye in the samples is at the bottom of the gel.

	Agarose gel electrophoresis - Wikipedia, the free encyclopedia
		Agarose gel electrophoresis is a method used in molecular biology to separate DNA strands by size, and to estimate the size of the separated strands by comparison to known fragments (DNA ladder).
		The central dye in agarose gel electrophoresis is ethidium bromide, usually abbreviated as EtBr.
		DNA-based gel electrophoresis can be used for the separation of DNA fragments of 50 base pairs up to several megabases (millions of bases).

	Protein gel electrophoresis
		This material is accompanied by a presentation on protein structure and principles behind denaturing samples and discontinuous gel electrophoresis.
		SDS (also called lauryl sulfate) is an anionic detergent, meaning that when dissolved its molecules have a net negative charge within a wide pH range.
		In a gel of uniform density the relative migration distance of a protein (Rf, the f as a subscript) is negatively proportional to the log of its mass.

	C43 SDS Polyacrylamide Gel Electrophoresis
		Electrophoresis of proteins in the presence of detergents leads to separation based upon molar mass.
		A lower concentration "stacking" gel, which is very porous, is used to concentrate the protein bands before they enter the running gel.
		In a more specific approach to detection, the gel is placed in a tray of transfer buffer prior to a Western blot (C-44).

	Untitled Document
		Polyacrylamide gels have smaller "pores" than do agarose gels, and so they do a better job of resolving protein molecules.
		Just as with agarose gels for DNA fragment analysis, a set of standards (protein markers of known sizes) is run alongside the samples to help you estimate the sizes of the proteins that you see.
		Once the gels are done, the gel "sandwich" is taken apart and the gel place in the western blot apparatus to transfer the proteins to a membrane.

	Western Blot - Gel Electrophoresis and Western Blot Theory
		Gels can be of constant density or they can be variable (gradient gels).
		Electrophoresis involves applying an electric current to the gel and allowing the proteins to migrate though the matrix.
		The amount of bound SDS is relative to the size of the protein, and the proteins have a similar charge to mass ratio.

	SDS-PAGE
		The environment of choice is polyacrylamide, which is a polymer of acrylamide monomers.
		A polyacrylamide gel is not solid but is made of a laberynth of tunnels through a meshwork of fibers (figure 2).
		The gel (gray box) has five numbered lanes where five different samples of proteins (many copies of each kind of protein) were applied to the gel.

	Experiment 8
		Electrophoresis is a technique that is widely used in biochemistry and biotechnology for the separation and characterization of proteins, DNA, and other charged molecules.
		The detergent SDS binds to all regions of the polypeptide causing it to unravel, or denature.
		Typically, R-250 is used to stain SDS polyacrylamide gels and G-250 in the Bradford assay.

		The polyacrylamide gel is formed by co-polymerization of acrylamide monomer CH and a cross-linking monomer N,N'- methylene bisacrylamide, CH (bisacrylamide).
		Usually gels with 10-15% acrylamide are used and the ratio bisacrylamide:acrylamide is 2.7-3.3%.

		Fill the other two edges of the gel cast adjacent to this edge with spacers in the same way, and hold them in place using two of the smaller clamps on each side, one near the bottom and one at the junction of the two spacers.
		Once the stacking gel has thoroughly polymerized, remove the comb very gently (the stacking gel is low enough in acrylamide concentration that the lane dividers will tear easily).
		Once the agarose has solidified, fix the gel in the gel box by draping two lengths of rubber hose across the gel box at the center, and slide the gel cast into the box, with the lanes facing the negative (fl) electrode.

	CHP - SDS-PAGE
		SDS is a detergent that dissociates and unfolds oligomeric proteins into its subunits.
		The SDS binds to the polypeptides to form complexes with fairly constant charge to mass ratios.
		The electrophoretic migration rate through a gel is therefore determined only by the size of the complexes.

	SDS POLYACRYLAMIDE GEL ELECTROPHORESIS (SDS-PAGE) (Site not responding. Last check: 2007-10-30)
		Electrophoresis is the migration of charged molecules in solution in response to an electric field.
		Their rate of migration depends on the strength of the field; on the nett charge, size and shape of the molecules and also on the ionic strength, viscosity and temperature of the medium in which the molecules are moving.
		Polyacrylamide, which is easy to handle and to make at higher concentrations, is used to separate most proteins and small oligonucleotides that require a small gel pore size for retardation.
	www.uct.ac.za /microbiology/sdspage.html (1204 words)

	[No title]
		Since larger proteins have a harder time passing through the pores in the gel, at the end of electrophoresis the smaller proteins will be closer to the bottom of the gel and the larger proteins will be closer to the origin.
		The stacking gel is generally of a low concentration, causing all proteins to move quickly through it and slow down rapidly at the resolving gel.
		Following electrophoresis, the gel must be fixed in order to prevent diffusion of proteins within the gel and stained in order to visualize the proteins.

	Lab12
		The higher the acrylamide concentration is, the smaller the pores of the gel are, and the slower proteins move.
		Therefore, gels with high concentrations of acrylamide are used to resolve small sizes of proteins, and gels with low concentrations of acrylamide are used to resolve big sizes of proteins.
		During the transfer, the gel is at the negative electrode side and the nitrocellulose membrane at the positive electrode side.

		SDS carries out this task by wrapping around the polypeptide backbone (Purves 1998.) Because proteins come in all shapes, folds and coils, it is important to even the playing field by transforming all molecules to their primary, linear structure (FIG.
		Polyacrylamide is a polymer of acrylamide monomers (Campbell 1998).
		Polyacrylamide, rather than agarose, is the medium of choice for separating proteins by size because its small pore size is necessary for retardation of small molecules (Purves 1998).

	Lab #4 - Estimation of Protein Molecular Weights by SDS-PAGE
		In SDS-polyacrylamide gel electrophoresis, SDS-PAGE, proteins are coated with an anionic detergent, sodium dodecyl sulfate.
		The polyacylamide gel is placed in an electric field, and the protein applied to the gel will migrate towards the positive electrode.
		The rate of migration is dependent on protein size; the movement of longer polypeptides is restricted by the polyacrylamide matrix, while smaller proteins migrate through the gel easier.

	Two-dimensional gel electrophoresis
		Two-dimensional gel electrophoresis (2-D electrophoresis) is a powerful and widely used method for the analysis of complex protein mixtures extracted from cells, tissues, or other biological samples.
		Since different types of samples differ in their ion content, it is necessary to adjust the IEF buffer and the electrical profile to each type of sample.

		It is important that the spacers are aligned properly, with the ends flush with the top and bottom edges of the plates, and the flanged edge of the T-shaped spacer positioned against the outside edges of the glass plate.
		Fill a 50-ml syringe with the solution and slowly inject it into the caster until the gels are 6 cm high, allowing 1.5 cm for the stacking gel.
