Strukturbestimmung von Proteinen

BioSAXS-2000

Die BioSAXS-2000 SAXS Kamera von Rigaku wurde speziell für die Anforderungen von Strukturbiologen entwickelt. Auf der Basis des patentierten, zweidimensionalen Kratky-Designs besitzt das BioSAXS-2000 einen geringeren Platzbedarf im Vergleich zur konventionellen 3-Lochkamera, bietet jedoch bessere Fluxcharakteristika. Der größte Vorteil jedoch liegt darin, dass das BioSAXS-2000 auf den offenen Port des Drehanoden-Röntgengenerators von Rigaku montiert werden kann. Die bestehende Ausstattung kann so voll genutzt werden. Zusätzlich kann das BioSAXS-2000 mit einer versiegelten Mikrofokus-Röntgenröhre von Rigaku gekoppelt werden. Die AUTO-Konfiguration des BioSAXS berücksichtigt dabei zwei zeitsparende Eigenschaften: einen automatischen Probenwechsler für den unbeaufsichtigten Betrieb über Nacht sowie eine automatische Analysen-Pipeline auf der Basis des weltweit gültigen Standards des ATSAS Pakets von EMBL (Hamburg).

Kein Grund auf Synchrotron-Messzeiten warten zu müssen

Das BioSAXS-2000 ist mit der neuen OptiSAXS Optik ausgestattet, einem optischen System mit Doppelfokus-Mehrschicht-Technologie und Detektor-Fokus. Im Vergleich zu seinem Vorgänger verbessert das OptiSAXS den Flux um mehr als das Doppelte, was zu höherer Punkthelle in Probenposition und schnellerer Datensammlung im Minutentakt führt. Somit liefert das BioSAXS-2000 Messergebnisse aus SAXS Experimenten in Kleinlaboratorien, die so bisher sonst nur von fortschrittlichen Synchrotrons erzielt werden konnten.

Sonderzubehör

  • Automatischer Probenwechsler (ASC) für 8 bis 96 Proben. Siehe hierzu [Zubehör] für ausführlichere Details.
  • Automatische Analysen-Pipeline (AAP) auf der Basis von ATSAS, der weltweit beliebtesten SAXS-Analyse-Software, entwickelt von EMBL (Hamburg). Siehe hierzu [Zubehör] für ausführlichere Details.

Features

  • Automatische Probenbühne mit drei Kapillarzellen und einer Standardposition für Pulver.
  • Simultane SAXS und WAXS Messungen (qmax = 0.65 Å⁻¹).
  • Einfache Installation mittels verfügbarem Generatoranschluss. Kann wahlweise auch an eine Röntgenquelle angeschlossen werden: Versiegelte Mikrofokus-Röntgenröhre, MicroMax-007 HF, FR-X.
  • Punktfokus-Optik verhindert mögliche Präzisionsprobleme in Verbindung mit traditionellen Kratky-Kameras.
  • Alle Systemkomponenten k&oml;nnen vom Steuerrechner betrieben werden.
  • Photodioden-Beamstop für Intensitätsmessungen und Probenabsorptionskorrigierung.
  • System mit Proben-Temperaturkontrolle.
  • 2D Kratky-Kollimation berücksichtigt Messungen niedriger q-Werte auch ohne Systemneuausrichtung.
  • SAXSLab Datensammlung und Verarbeitungssoftware.

Below are the specifications for the BioSAXS protein small angle scattering X-ray system from Rigaku.


  • Incident Beam: OptiSAXS CMF focusing optic
  • Collimation: 2D Kratky (X stage and tilt, motorized)
  • Beam size at Sample: Variable Width x 1.5 mm²
  • Sample Stage: 3 capillaries (X, Y stage, motorized) with a flow cell option
  • Sample Volume: 20 – 30 μL
  • Sample Temperature Control
  • Beam Stop: PIN diode detector (motorized)
  • q-range: 0.006 Å⁻¹ - 0.6 Å⁻¹
  • Detector: Rigaku HyPix-3000 Hybrid Pixel Array Detector (pixel size: 100 μm, active area: 77.5 mm X 30.5 mm)

Because data collection is faster with the BioSAXS-2000, automated tools for sample mounting, data collection and data analysis become especially important. The BioSAXS AUTO package accomplishes each of those tasks with the Automated Sample Changer (ASC) for automatic sample loading and data collection, and the Automated Analysis Pipeline (AAP) for automatic data processing and analysis.

Description
Automatische Daten-Analysenpipeline

Das AAP nutzt den Industriestandard des ATSAS Pakets um folgende automatisierte Analysen für jede Analysee zu ermöglichen:

  • Automatische Probenauswertung und Identifikation des Aggregationsverhaltens
  • Automatische Mittelwertbildung des Tiefeprofils und Puffersubtraktion
  • Automatische Erstellung von Guinier-Funktionen und Berechnung von Rg and I(0)
  • Automatische Erstellung von Kratky-Funktionen
  • Automatische Berechnung von Porod-Volumen und Molekulargewicht (MW)
  • Automatische Berechnung von P(r) mit Berichterstattung von Rg und Dmax im Realraum
  • Automatische Hüllkurvenberechnung, Mittelwertberechnung und Analyse
  • PDF-Fertigungsberichtgenerator und einfache Übersicht vorangegangener AAP Durchläufe
Das AAP erlaubt rasche Auswertungen der Probenqualität, mit Wiedergabe farbkodierter Ergebnisse. Die Identifizierung und Abgrenzung von Proben mit günstigem Analyseverhalten gegenüber solchen mit negativem Aggregations- oder Konzentrationsverhalten kann somit einfach und rasch vonstatten gehen. 		Automatische Daten-Analysenpipeline
Automatische Probenhandhabung

Das ASC bietet wartungsfreie Probenaufbringung und Datensammlungen für Laboratorien, die besonderen Wert auf eine höhere Durchsatzleistungsfähigkeit des BioSAXS-2000 legen. Das ASC unterstützt dabei die Probenaufbringung mittels 96-Positionshalterung oder 0.2 ml PCR Röhrchenhalterung, wobei ein nahtloser Übergang von Hardware und dem SAXSLab-Software-Paket gewährleist wird.
Probenlösungen können folienversiegelt werden um ein Verdunsten des Lösungsmittels vor der Datensammlung zu verhindern. Das ASC unterstützt darüberhinaus eine temperaturfgeführte Pobenlagerung, mehrere Reinigungsprozesse und Reinigungsprotokolle.

 Automatische Probenhandhabung

Together, the ASC and AAP components of the BioSAXS AUTO package allow unattended sample mounting, data collection and processing to give you a more beamline-like experience, and to allow you to focus more time where it counts: SAXS data analysis and publication of results.

OptiSAXS

Focuses and monochromatizes an X-ray beam for small angle X-ray scattering


Rigaku's OptiSAXS optic is the latest generation of Cofocal Max-Flux® (CMF) optic for the BioSAXS-2000 SAXS system configured with a Rigaku microfocus rotating anode generator. The long length of the OptiSAXS optic allows it to capture more of the X-ray beam from the microfocus generator resulting in higher flux. As a result, the OptiSAXS optic delivers an intense, monochromatic X-ray beam with greater than two-fold higher flux compared to its predecessor.

Features

  • Graded, multilayer confocal optic with increased length for maximum beam intensity.
  • Double-bounce beam geometry for optimum beam purity
  • Designed to achieve maximum performance when coupled with Rigaku microfocus X-ray generators
