Protein extraction kit, Insect PE LB™

Catalog Number: (786-411)
Supplier: G-Biosciences
Description: Insect PE LB™ has been developed for extraction of total biologically active, soluble proteins from adherent or suspension cultured insect cells, including Sf9 and Sf21. Insect PE LB™ utilises a mild non-ionic detergent and a proprietary combination of various salts and agents to enhance extraction and stability of proteins. The Insect PE LB™ is fully compatible with downstream processes, such as electrophoresis and chromatography. Depending on the required downstream application, additional agents such as reducing agents and protease inhibitors may be added into Insect PE LB™.

Glycerine ≥99%, clear colourless viscous liquid cell culture reagent

Supplier: MP Biomedicals
Description: Storage: Store at Room Temperature (15 - 30 °C)
Glycerol is used both in sample preparation and gel formation for polyacrylamide gel electrophoresis. Glycerol (5-10%) increases the density of a sample so that the sample will layer at the bottom of a gel’s sample well. Glycerol is also used to aid in casting gradient gels and as a protein stabilizer and storage buffer component. Glycerol is used in the concentration and storage of enzymes. Also prevents back-diffusion and protein samples into the buffer. Ideal for use as a cryoprotectant.

Dithiothreitol (DTT, Cleland's reagent) ≥99.5%, white powder for electrophoresis

Catalog Number: (ICNA04856126)
Supplier: MP Biomedicals
Description: DL-Dithiothreitol is also known as Clelands reagent; Protective agent for sulfhydryl groups (-SH). Quantitatively reduces disulfides (-S-S- to -SH). In this reaction the DTT is oxidized to the cyclic disulfide which ensures the reduction of other disulfides in solution. Disulfide reduction occurs quickly at pH 8.
Dithiothreitol is useful for stabilizing sulfhydryl containing enzymes. Effective in sample buffers for reducing protein disulfide bonds prior to SDS-PAGE. DTT can also be used for reducing the disulfide bridge of the cross-linker N,N'-bis(acryloyl)cystamine to break apart the matrix of a polyacrylamide gel. DTT is less pungent and is less toxic than 2-mercaptoethanol.
Useful for stabilizing sulfhydryl-containing enzymes.

2D Clean-Up kit

Catalog Number: (80-6484-51)
Supplier: Cytiva
Description: The 2-D Clean-Up Kit is designed to prepare samples for 2-D electrophoresis that otherwise produce poor 2-D spot-maps due to high conductivity, high levels of interfering substances, or low protein concentration. The reagents quantitatively precipitate proteins while leaving interfering substances, such as detergents, salts, lipids, phenolics, and nucleic acids, in solution.

Coomassie® brilliant blue R-250

Supplier: Thermo Fisher Scientific
Description: Thermo Scientific Pierce coomassie brilliant blue dyes are composed of one of the most common forms of coomassie dye, which is a key component of various colorimetric protein gel stains. Coomassie R-250 and G-250 dyes are two chemical forms of a disulphonated triphenylmethane compound that is commonly used as the basis of stains for detection of proteins in gel electrophoresis and bradford-type assay reagents for protein quantitation. The R-250 (red-tinted) form lacks two methyl groups that are present in the G-250 (green-tinted) form, which is also called colloidal coomassie dye.
