Protein Quantification Kit

PQK-Rapid utilizes the color change of Coomassie Brilliant Blue-G dye in the range of 465 nm to 595 nm Coomassie Brilliant Blue-G binds to basic or aromatic amino acid residues of proteins in an acidic condition Since this kit requires only 30 seconds of incubation time the measurement of protein concentration can be carried out within a few

She now produces a wide range of scientific content including regular features for Biocompare May 27 2020 Although modern approaches to western blotting follow the same principles pioneered by the inventors of the technique—namely the separation of proteins on a gel and subsequent transfer to a membrane followed by antibody-based detection—researchers now have access to many new

Coomassie Blue detection Protease Activity (Protein Markers Ladders) - A 20 l sample of Color Prestained Protein Standard Broad Range (11-245 kDa) incubated for 16 hours at 37C results in no detectable degradation of the protein mixture as determined by SDS-PAGE with Coomassie Blue detection PS-P7712S/L v1 0 Page 1 of 1 Derek Robinson

Coomassie™ Blue silver stain ethidium bromide (EtBr) and Deep Purple™ Total Protein Stain Camera lens and CCD chip: A bright wide aperture FUJINON™ F0 85 lens specially developed for chemiluminescent imaging projects sharp images onto a octagonal pixels the gap between pixels in the horizontal and vertical planes is reduced This pattern gives an effective image resolution of 6 3

Specific enzyme detection following isoelectric focusing as a run in parallel to those destined for Coomassie Blue staining were subjected to specific enzyme detection cod and blue whiting The pH region in the 5-6 range proved to be specific in all the species tested

DCB™ Protein Assay is a Coomassie Dye (Bradford) based detergent compatible assay The Assay contains proprietary reagents suitable for samples containing detergents including SDS and Triton-X 100 DCB™ Protein Assay is simple and rapid to perform with reaction optimum time of 5 minutes

Coomassie Brilliant Blue agar was shown to be a suitable differential presumptive medium for diagnostic and epidemiological studies on fish and water samples though it is effective only for A+ isolates not the uncommon A- isolates A salmonicida isolates were the only cultures appearing dark blue when grown in combination with A hydrophila or Yersinia ruckeri

Q coomassie blue staining solution에 대한 질문이 있습니다 coomassie blue staining methods에서 각각의 solution에서 들어가는 것들 중에서 methanol과 glacial acetic acid의 grade가 궁금합니다 : A Coomassie 염색에 사용하는 methanol과 acetic acid는 grade와는 상관이 없습니다 덕산에서 깡통으로 판매하는 것을 구매해 사용하면

Description Thermo Scientific™ GelCode Blue Stain Reagent is a ready-to-use protein stain based on colloidal coomassie dye G-250 that provides nanogram-level detection and results that exceed the clarity obtained with typical coomassie stains

Organic dyes such as Coomassie Blue R (GBR) and G types (GBG) are often used to visualize proteins separated by 1D- or 2D-PAGE Coomassie Blue is easy to use shows linearity of detection over a 10-50-fold range of concentration and is highly compatible with downstream protein identification methods such as MS (Patton 2002 Simpson 2003 and references therein)

Mechanism of Coomassie brilliant blue G-250 binding to proteins: A hydrophobic assay for nanogram quantities of proteins Anal Bioanal Chem 391: 391–403 Glazier S A and J J Horvath 1995 Feasibility of fluorescence detection of tetracycline in media mixtures employing a fiber optic probe Anal Lett 28: 2607–2624

GelCode Blue Stain Reagent uses the colloidal properties of coomassie G-250 dye for polyacrylamide gel protein staining This unique reagent stains only protein and unlike traditional coomassie stains based on the R-250 form of the dye allows bands to be viewed directly on the gel during the staining process After staining an optional water-wash step further enhances staining sensitivity

Coomassie blue staining and immunoblotting revealed that the four proteins were successfully separated and transferred for analysis This gel system is simple to prepare and easy to use and it is a reliable method for analyzing myofibrillar proteins or other protein mixtures with broad molecular masses

The assay is based on the observation that the absorbance maximum for an acidic solution of Coomassie Brilliant Blue G-250 shifts from 465 nm to 595 nm when binding to protein occurs Both hydrophobic and ionic interactions stabilize the anionic form of the dye causing a visible color change The assay is useful since the extinction coefficient of a dye-albumin complex solution is constant

Finally when applied to real biological samples using the LICOR Odyssey quantitative scanning system total protein analysis (using coomassie) was linear in its detection across a broader range of protein loading than either actin or tubulin (1 to 40 ug Figure 4G H) The coefficient of variations for both Bicinchoninic Acid solution (BCA) assay and total protein analysis were 0 979 and 0
