International Year of Crystallography

INTERNATIONAL YEAR OF CRYSTALLOGRAPHY - 100 years since Nobel Prize for X–ray diffraction

In 1914, the Nobel Prize in Physics was awarded to Max von Laue for making the connection between X–ray diffraction angles and the size and orientation of spacing between units in a crystal. In 2014, the United Nations General Assembly adopted a resolution proclaiming this year as the International Year of Crystallography. UNESCO and the International Union of Crystallography have been invited to facilitate this proclamation and have put together a year–long program.

CRYO SHUTTER - Annealing is a promising technique to improve poorly diffracting crystals

Cooling your sample to cryo–conditions helps protect the structure of a crystal from radiation and thermal motion. Poor cryo–cooling can increase the sample's mosaicity, leading to poor diffraction data. A brief interruption of the cryo–stream can warm then re–cool the crystal and potentially reduce mosaicity.
The Cryo Shutter, developed by Dr. Uwe Mueller, MX-Lab at BESSY-II, HZB Berlin-Adlershoto is an automated system for crystal annealing, ready for installation on Cryojet (Oxford Instruments) and Cryostream 700 Systems (Oxford Cryosystems).

• Precise interruption of the cryostream
• Reproducible crystal annealing
• Extremely fast closing and opening of the shutter prevents turbulences



IN SITU PLATE - The revolutionary 96-well SBS format crystallization plate like no other

The plate's design allows you to: 
• Use your current robot to populate
• Setup sitting or hanging drops with the robot
• You can choose from 1 to 6 growth drops per well
• Use from 50 nl - 2 µl size drops
• Obtain more hits and reproducible results
• Use X-rays to screen crystals for diffraction before harvesting
• Get better results from UV screening
• Transport your crystals safely to the synchrotron



THE MICRORT™ SYSTEM - Easily screen crystals at room–temperature before cryoprotecting and freezing

Room–temperature screening is especially important in protein crystallography, as many low–temperature data sets do not yield diffraction data of sufficient quality to determine a structure. MiTeGen’s patented MicroRT™ system allows you to screen your samples for improper crystal alignment due to damage or poor as–grown crystal quality before you head to the beamline. Introducing routine room-temperature screening of your crystals can easily save your experiment time, money, and effort.


• 1 MicroRT™ Tubing Kit (20 1.5” (37 mm) long clear polyester capillaries sealed at one end; Extra–keen razor blades for cutting tubes to desired length; Small tube of grease for lubricating the base)
• 1 MicroRT™ Aligner for properly setting the capillary tube over the crystal and onto the base
• 1 box of 20 Dual-Thickness MicroMounts™
• 1 pair of serrated-end tweezers

• Allows rapid screening of crystals at room temperature, to help maximize the efficiency of your crystallography pipeline.
• Easy sample mounting with little risk of crystal loss or damage.
• Easy collection of both room and low-temperature data from the same sample.
• Easy sample visualization and alignment, especially for small crystals.
• Capillary tubing is easily cut and sealed, and gives significantly less background X-ray scatter than glass capillaries.
• One size capillary fits all, and capillaries are reusable, lowering your cost per measurement.

ProtoGel (30%) - 1 Litter

37.5:1 Acrylamide to Bisacrylamide Stabilized Solution

Optimized for SDS-PAGE of Proteins (Laemmli gels)
Consistently Crystal Clear Gels, Zero Fluorescence
Stabilized for Long Shelf Life

Catalog Number: EC-890

ProtoGel-30percent-1Litter ProtoGel forms an electrophoresis matrix that is ideal for the separation of proteins and polypeptides. ProtoGel is a stabilized, ready-to-use 30% (w/v) acrylamide/methylene bisacrylamide solution (37.5:1 ratio), manufactured from the highest quality materials, from which virtually all impurities have been removed. ProtoGel has zero acrylic acid content, eliminating the fixed charges that cause band streaking. Additionally, oxidation products such as aldehydes have been removed by a selective adsorption process. Aldehydes can attack proteins, altering the structure of the sample, and thus altering Rf values. With ProtoGel, you can trust that your results will be consistent one electrophoretic run to the next.

Storage: ProtoGel is stable for 24 months when stored tightly capped in a dark area at room temperature (20°C).

ProtoGel (30%) Protocol
Measure and Mix Solutions:
The volume of ProtoGel required for gel casting solutions of any volume and acrylamide concentration may be calculated from the following formula:
Vp =(X) (Vt)/30
Vp = Volume of 30% ProtoGel
X = % Monomer Desired in Gel
Vt = Total Volume of Gel Casting Solution

EXAMPLE: To make 100 ml of a 10% monomer gel, calculate the volume of Protogel to add as follows:
Vp = (10) (100)/30 = 33.3 ml

Initiate and Cast Gel:
For optimal results degas gel solution for 10 minutes under vacuum aspiration prior to innitiation with APS and TEMED. Add 1.0ml of 10% (w/v) ammonium persulfate for every 100ml of gel casting solution. Swirl gently to mix. Add 0.1 ml of TEMED for every 100ml of gel casting solution. Swirl gently to mix. Pour the solution into the gel casting cassette. The gel should begin to set in 10-20 minutes. To provide a sharp interface, overlay the gel with water saturated n-butanol during polymerization. Flush butanol away with water just before casting the stacking gel (below).

Cast Stacking Gel:
Use ProtoGel Stacking Buffer to make 10ml of a 4% stacking gel:
ProtoGel: 1.3ml
ProtoGel Stacking Buffer: 2.5ml
Deionized Water: 6.1ml
Add 0.05ml 10% Ammonium Persulfate and 0.01ml of TEMED. Gel will begin to set in 20 minutes.

DNA Polymerases - For Regular Applications : BIOTAQ DNA Polymerase

  • Routine PCR applications
  • TA cloning

BIOTAQ™ is widely used by molecular biologists that have come to depend upon the robust performance of this reagent.

BIOTAQ is a highly purified thermostable DNA polymerase offering very high yield over a wide range of PCR templates (Fig. 1), and is the ideal choice for most assays. BIOTAQ is a robust preparation and consistently delivers high yields with minimal background. BIOTAQ possesses 5´-3´ exonuclease activity and leaves an ´A´ overhang such that the PCR product is suitable for effective integration into TA cloning vectors.

BIOTAQ is supplied with 10x NH4-based Reaction Buffer, which provides optimal conditions for most experiments. Additional MgCl2 is provided to allow reaction conditions to be adjusted to suit the template.

The specificity and performance of BIOTAQ can be further improved with the use of 2x PolyMate Additive which is designed for GC- or AT-rich DNA, "dirty" templates or sequences with a high level of secondary structure.

BIOTAQ™ DNA Polymerase is purified from Thermus aquaticus.

Unit Definition

One unit will incorporate 10nmoles of dNTPs in 30min at 72°C.

Storage Conditions

BIOTAQ can be stored for 12 months at -20°C.

RunBlue DTT Reducer - 1ml

Catalog number : NXA32001 
Availability: Yes 

Details: All RunBlue Buffers, Reagents and Accessories have been specifically designed and formulated for use with the RunBlue Gels and Apparatus to provide optimum performance and results.  Buffers are made usiong the highest qualtiy raw chemicals and have different compositions to other manufacturers buffers - only use RunBlue formulated buffers with RunBlue Gels.

RunBlue RAPID Running Buffer is a Reducing, Tris-MOPS buffer system which provides a seperation similar to a conventional MES buffer system and provides excellent separation of low molecular weight proteins.  The RunBlue SDS Running Buffer is a Non-Reducing Tris-Tricine buffer system which provides a separation similar to a conventional MOPS buffer system and provides increased separation of higher molecular weight proteins.  Simply choose which buffer will provide the greatest resolution for your protein(s) of interest - see image below.

SDS-vs-RAPID-Buffers Plain

Included with the reagents are RunBlue Prestained Markers.  These protein standards have been conjugaded to dyes to enable visualisation of the marker bands in the tank and prior to staining to allow you to see where your protein has reached (very useful for very small proteins!).  In addition, the RunBluePrestain Markers contain two standards (71 & 28 kDa) that have been conjugated to an orange dye to easily see which marker is which during running.

RunBlue Prestained Markers also offer a quick and convenient method to confirm transfer efficiency when blotting and to compare molecular weight with identity when labelling the protein band.
