Fernandez-Patron, C., Castellanos-Serra, L., and Rodriguez, P., BioTechniques, 12 564 (1992). j SYPRO is a trademark of Molecular Probes, Inc., Eugene, OR. k SYPRO Ruby IEF stain requires an overnight incubation. [Pg.136]

IPGs into mirrors. An easy way to stain IPGs is to immerse them for 1 h in colloidal CBB G-250 followed by two 10-min water washes. There is also a version of SYPRO Ruby stain specifically formulated for use with both carrier ampholyte and IPG-IEF gels. [Pg.148]

CBB G-250 is another popular total protein stain. Researchers blotting 2-D PAGE gels particularly favor it because it is compatible with mass spectrometry. Stained blots provide good media for archiving 2-D PAGE separations. A version of SYPRO Ruby, formulated for blots, is a very sensitive total protein stain. [Pg.153]

Figure 5.1 Two-dimensional electrophoresis separates potato proteins based on their isoelectric points and molecular weights. Using a wide-scale pH gradient and large gels, 1000-2000 quantifiable proteins can be separated. The gel stained with SYPRO Rubi shows soluble tuber proteins of potato cultivar Sante.

This is an entirely gel-based procedure no mass spectrometry is involved. Proteins from the two comparison samples are separated by a 2-DE protocol and images of the stained spots are captured after staining the gels with a suitable dye (e.g., CCB or SYPRO Ruby) next, the measured densities of the spots are compared using image analysis software to provide differential expression of proteins.44 45 Identification of proteins is accomplished as mentioned in Section 9.12.3. [Pg.467]

Sypro Ruby Protein Blot stain (Cat. No. S-11791 Invitrogen/Molecular Probes). [Pg.116]

The limited volume of the total cellular material from biopsy samples makes it necessary to use a slight modification of the lysis buffer recipe as compared with the cell culture lysis buffer. The following protocol describes a method for preparing whole cell lysates from LCM cells. The limited biopsy sample generally precludes the use of total protein assays before microarray printing. To compensate for this, one microarray slide is stained for total protein using a Sypro Ruby Protein blot stain (see Subheading 3.3.3.). [Pg.118]

Each microarray is probed with a single primary antibody directed against the protein of interest. Microarray slides used for immunostaining should be blocked before staining. Microarray slides used for Sypro Ruby protein staining do not require blocking. [Pg.121]

Sypro Ruby blot stain is a ruthenium complex, exhibiting luminescence upon excitation with either UV-B or blue light. The luminescence may be visualized with UV epi-illumination sources, UV or blue-light transilluminators, or laserscanning instmments with excitation light at 450, 473, 488, or 532 nm. The emission peak of the ruthenium complex is approximately 618 nm (24). [Pg.124]

Figure 4. Comparative proteome analysis of L. donovani infantum axenic promastigotes and amastigotes. Proteins from whole cells were extracted as described in Figure 2, run on narrow-range IPG strips, and stained with SYPRO Ruby (Molecrdar Probes) to allow quantitative comparisons. Representative gels of each stage are shown. The expanded region contains a number of differentially-expressed spots. Spots marked with orange arrows appear to be stage-specific, while spots marked with blue arrows are differentially expressed. Figure 4.

As with the gel stain, fluorescent colors have also caused a small revolution in blot staining. SYPRO Ruby stains proteins on PVDF or nitrocellulose with almost the same sensitivity as gold—certainly with more sensitivity than Coomassie and India ink. Staining takes just about three quarters of an hour bathe nitrocellulose membranes for 2 x 10 minutes in 7% acetic acid and 10% methanol, and then stain for 15 minutes with SYPRO Ruby and finally wash with water for 6 x 1 minutes. [Pg.18]

Fig. 1. Two-dimensional gel electrophoresis of culture supernatant proteins. Proteins were isolated from wild-type Streptococcus pyogenes strain NZ131 after 18 h of culture in 40 mL of chemically defined medium. Hundred micrograms of protein was separated with a 7-cm immobilized gradient strip (pH 4-7) (IPG GE Biosciences) and SDS-PAGE. Proteins were stained with SYPRO Ruby. Fig. 1.
