Image Unavailable-IB40075

Ethidium bromide 10 mg/mL in aqueous solution for molecular biology

Catalog Number: (IB40075)
Supplier: IBI Scientific
Description: Used to detect both single- and double-stranded nucleic acids (both DNA and RNA). Does not intercollate into single-stranded DNA very well; therefore, the fluorescence of single-stranded DNA is relatively poor in comparison to double-stranded DNA. The recommended final concentration of ethidium bromide in agarose gels and electrophoresis buffers is 0.5µg/mL.

Pierce™ Silver Stain Kit, Thermo Scientific

Catalog Number: (PI24612)
Supplier: Invitrogen
Description: The Pierce Silver Stain Kit is a rapid, ultra-sensitive, and versatile silver stain system for protein detection in polyacrylamide gels, yielding consistent and reliable results. It is a metallic silver (Ag) protein stain that yields a remarkably clear and uniform gel background. In standard mini gels, proteins are detectable at greater than 0.25 ng per band or spot. The protocol has been optimized for flexibility by allowing short or overnight gel fixation and staining steps without affecting staining performance (sensitivity or clarity). A short (one-minute) sensitization step, performed after gel fixation, yields results that are free of the characteristically dark or blotchy backgrounds often seen with homemade or other commercially available silver stains. This feature is beneficial when performing densitometric analysis of silver stained gels.

Agarose, white powder for electrophoresis

Supplier: MP Biomedicals
Description: Agarose is a purified linear galactan hydrocolloid isolated from agar or agar-bearing marine algae.
Agarose is useful in separation of nucleic acids electrophoretically because agarose gels have larger pore sizes than cross linked acrylamide gels at low concentrations and in chromatographic separations by either beading the agarose or cross-linking it. Agarose gels are also used in immunoelectrophoresis (IEP) and double-diffusion Ouchterlony plates to demonstrate antibody-antigen reactions. Agarose was used to prepare 0.5% agarose gel for Southern blot analysis of the DNA extracted from primate muscles.
The following is a list of properties associated with our agaroses: Sulfate content - used as an indicator of purity, since sulfate is the major ionic group present. Gel strength - the force that must be applied to a gel to cause it to fracture. Gel point - the temperature at which an aqueous agarose solution forms a gel as it cools. Agarose solutions exhibit hysteresis in the liquid-to-gel transition - that is, their gel point is not the same as their melting temperature. Electroendosmosis (EEO) - a movement of liquid through the gel. Anionic groups in an agarose gel are affixed to the matrix and cannot move, but dissociable counter cations can migrate toward the cathode in the matrix, giving rise to EEO. Since electrophoretic movement of biopolymers is usually toward the anode, EEO can disrupt separations because of internal convection.

Tris(hydroxymethyl)aminomethane (TRIS, Trometamol)

Supplier: MP Biomedicals
Description: Tris has been useful as buffers in a wide variety of biological systems. Uses include pH control in vitro and in vivo for body fluids and in buffering systems for electrophoresis applications. Tris has been used as a starting material for polymers, oxazolones (with carboxylic acids) and oxazolidines (with aldehydes). Tris does not precipitate calcium salts and is of value in maintaining solubility of manganese salts. It can be used for the direct standardization of a strong acid solution; the equivalence point can be determined either potentiometrically or by use of a suitable indicator such as 3-(4-Dimethylamino-1-naphthylazo)-4-methoxybenzenesulfonic acid. It is an auxiliary material in pharmaceutical science.
Store at Room Temperature (15-30 °C). Store dessicated.

Anti-Thymine Dimer Mouse Monoclonal Antibody

Catalog Number: (89350-012)
Supplier: Genetex
Description: Non-radioactive labeling of DNA is typically based on the enzymatic incorporation of modified nucleotides, carrying a small chemical moiety such as biotin, digoxigenin or fluorescein. These tags are subsequently detected by specific reagents such as streptavidin or a specific antibody coupled to a signal-producing enzyme. Although very efficient and reliable, labeling by in vitro polymerization is time-consuming, expensive, and may require various post-label purification steps to remove an excess of unincorporated precursors. An alternative strategy for DNA labeling, is based on the UV-induced formation of cyclobutane thymine dimers. Several methods have been described for the detection of thymine dimers, which are based on chromato-graphic analysis, and on biochemical analysis with endonucleases specific for UV-irradiated DNA. In addition, methods utilizing antibodies specific for pyrimidine dimers and other UV-induced DNA lesions have evolved, which permit the study of the induction and repair of these lesions without the requirement of in vivo radiolabeling of DNA. Photoimmunodetection, is a rapid, reliable and low-cost supplement to existing methods for nonradioactive DNA labeling. It enables a sensitive and non-radioactive method for labeling, detection, and quantification of high molecular weight (HMW) DNA fragments. The method is based on the introduction of thymine dimers into DNA after separa-tion by pulse field gel electrophoresis (PFGE), followed by detection with thymine dimer specific antibodies. The method does not require any enzymatic or chemical manipulation of the DNA sample. Monoclonal anti-bodies reacting specifically with thymine dimer, facilitate investigations on the apoptotic process and the role of UV-induced pyrimidine dimers in the process of photocarcinogenesis.

Urea ≥98%, white powder for molecular biology

Supplier: MP Biomedicals
Description: Applications:
Urea is used for the denaturation of proteins and as a mild solubilization agent for insoluble or denatured proteins. Useful for renaturing proteins from samples already denatured with 6 M guanidine chloride such as inclusion bodies and in the extraction of the mitochondrial complex. It is commonly used to solubilize and denature proteins for denaturing isoelectric focusing and two-dimensional electrophoresis and in acetic acid-urea PAGE gels. May be used with guanidine hydrochloride and dithiothreitrol (DTT) in the refolding of denatured proteins into their native or active form. Urea is used in cell or tissue culture media to increase the osmolality. Urea has also been used as fertilizer because of the easy availability of nitrogen; in animal feeds; it is reacted with aldehydes to make resins and plastics; condensed with malonic ester to form barbituric acid; used in the paper industry to soften cellulose.
Biochem/physiol Actions:
Urea has been shown to act as an aldosterone antagonist in the development of peanut agglutinin binding in cultured embryonic renal collecting duct epithelial cells. Urea is the principal end product of nitrogen metabolism in most mammals, formed by the enzymatic reactions of the Kreb's cycle.
Typical Working Concentration:
The use of 2 g/L urea in the culture of Kluyveromyces marxianus to produce a thermostable extracellular lipase has been described. Urea is typically used at a concentration of 8 M for protein denaturation or solubilization. A final concentration of 5 M urea is commonly used in molecular biology for sequencing gels. To prevent carbamylation, do not heat urea containing buffers above 37 °C
