NEU: 4-Farben 2D-DIGE = Refraction-2D QPLEX

Refraction-2D QPLEX ist unsere neueste Entwicklung im Bereich 2D-DIGE.

4 leistungsstarke fluoreszierende G-Dyes bieten Ihnen ein leistungsstarkes
Werkzeug, um bis zu vier Proben gleichzeitig analysieren zu können. Sie
benötigen damit 30% weniger Gele als bei dem herkömmlichen 3-Farben DIGE.

Quantitative Western Blots = Smart Protein Layers

The first standard-based technology for quantitative Western Blots and absolute quantification of 1D gels

Diesen Eintrag gibt es leider nur in englischer Sprache.

.

The problem

Quantitative Western blot analysis require an appropriate reference. Recent publications show that house-keeping proteins (ß-actin, ß-tubulin, GAPDH) are regulated under various conditions. Therefore, total protein is a more accurate reference. However, as protein is washed away from the membrane during WB procedure target and reference proteins must be detected at the same point of time.

.

The solution

Smart Protein Layers (SPL) is the new technology for stain-free, quantitative and standardized analysis of protein gels and Western blots. For the first time, the target protein and – as a reliable reference – the amount of total protein of this sample can be detected at the same time. In addition, SPL allows to precisely compare data derived from different experiments.

.

SPL combines

  • the Smart Label for high sensitivity total protein visualization during every step of electrophoresis and Western blot procedure.
  • the Smartalyzer, a sample-specific fluorescent standard for precise normalization and quantification of 1D protein gels and Western blots within one experiment
  • the Calibrator, a gel- and blot-specific standard to compare data from different experiments. Works also as a fluorescent MW ladder.

.

For 1D gels the Smart Protein Layers allow you to run as little as 1-2 µg of total protein per lane and to detect (without staining and destaining) as many protein as with the 10 fold amount of protein visualized by Coomassie staining. Compared to silver, the dynamic range (range between non-saturated and saturation) is 1,000 fold higher.

For quantitative Western blots, the Smart Protein Layers are the reliable reference for your target protein expression. To detect your target protein keep your method of choice such as chemiluminescence or the usage of primary/ secondary fluorescent antibody conjugates.

Ministerpräsidialer Besuch

Am Montag den 05.05.2014 besuchte der Ministerpräsident des Landes Sachsen-Anhalt Dr. Reiner Haseloff NH DyeAGNOSTICS. Ministerpräsident Haseloff verschaffte sich in einem zweistündigen Besuch einen persönlichen Eindruck über neuesten Entwicklungen von NHD. Wichtiger Teil des Arbeitsgespräches waren nächste Schritte zum FuE-Projekt PIGchip, welches einen Schnelltest für Eberfleisch während der Schlachtung ermöglichen soll.

Smart Protein Layers

Are you using total protein as "loading control" for target normalization of Western Blots? Superb!

But when do you detect the total protein?

.

Fig. 1. PVDF membrane loaded with 6x 20 µg total protein from E. coli. Total protein was relabeled with Smart Label Red and detected using an Octoplus QPLEX Imager.

.

30-60% of the total protein on a Western blotting membrane is washed away during the several antibody-incubation and washing steps.

Reliable quantification of Western blots therefore requires total protein detection (for normalization) at the point of time the target is detected.

Smart Protein Layers offers real-time total protein detection and many other features.

BEO Dry Blotter für höchste Performance

Der Beo Dry Blotter wurde von uns für das Blotten der Velum™ XLS, IEF und Silver-Gele entwickelt. Das Blotting basiert auf Druck- bzw. Kapillar-Effekten und benötigt nicht, wie bei anderen Blottern Minuten, sondern geht am besten über Nacht. Das Ergebnis jedoch spricht für sich: Blots in allerhöchster Qualität, ohne jegliche Störeffekte.

Das Handling des Beo Dry Blotters ist kinderleicht und funktioniert ohne Strom und Puffer. Dafür können Sie zeitgleich bis zu 3 Velum™ 1D-, IEF- oder 2D-Gele blotten oder wenn die Diplomarbeit fertig werden muß, auch 18 Mini-Gele.
