Gel Crusher Spin Column

 

  • Creates uniform gel fragments with no chunks
  • Fits in standard microtubes
  • Increases DNA yield
  • For use in molecular cloning, PCR, restriction digestions, sequencing, and labeling protocols
  • Fits 2 mL receiver tubes 

MTC Bio’s Gel Crusher Spin Columns are designed to replace labor-intensive gel fragmentation steps (crush+soak method, etc.). Commonly used in molecular cloning, PCR, restriction digestions, sequencing, and labeling protocols, these spin columns can be used to fragment gel slices (typically cut with a gel extractor or razor blade) into smaller pieces.

 

These smaller uniform pieces will produce greater yields and can be easily pipetted using wide bore tips into an NaCl solution. This reduces the time to create a fine slurry for further elution, filtration, incubation, etc. Place the Gel Crusher™ column in the 2 mL microtube and centrifuge the column/tube assembly in a standard benchtop microcentrifuge for 5 minutes at maximum speed (generally approximately 15,000 x g).

 

The gel will be forced through the 600 uM holes into the 2 mL receiver tube. The crushed fragments will be small enough to be aspirated/dispensed through a pipette tip.

 

Reversible Racks

  • Alphanumeric markings and are supplied in packs of 5.
  • Choose 60 well (5 x 12) or 96 well (8 x 12) formats
  • Reversible racks, accept 0.5 and 1.5 to 2.0 mL microtubes
  • Alphanumeric marking on each well
  • Made of polypropylene   

Azure ChemiWriter ECL Pen

 

Chemiluminescent pen for blot annotation

The Azure ChemiWriter ECL Western blot annotation pen is a chemiluminescent marker that enables you to write or draw on your transfer membranes, resulting in a chemiluminescent signal on your markings once substrate is added. Contains a reagent that reacts with HRP substrates to produce chemiluminescence and also a blue dye to allow you to see markings as you write on the Western blot.

Use for tracing visible protein ladders or making identifying marks on your Western blots. Pen has two tips on each end: one fine-tipped for thin markings and one thicker for depositing more of the reagent.


Quantity: 1 pen

 

Features

Enables you to write or draw on your transfer membranes. A chemiluminescent signal will be detectable from your markings once chemiluminescent substrate is added.

  • Use for tracing visible protein ladders or making identifying marks on your blots. Pen has two tips on each end: one fine-tipped for thin markings and one thicker for depositing more of the reagent.
  • There are two heads to the pen, a fine point tip and a thicker chisel point tip.
  • We recommend using the fine point tip to annotate the blot and mark protein ladders for detection.
  • The chisel point of the pen can be used to deposit an increased amount of reagent on the blot for more intense signal.
  • For best results we recommend annotating your blot after transfer and before starting your Western blotting protocol.
  • Once annotated, the blot may be stored dry or wet, refrigerated or at room temperature.
  • Storage: pen should be stored tightly closed at room temperature. ChemiWriter ECL reagent and blue ink markings on the blot are stable for at least three months.

Hoefer® Standard and Preparative Combs for Mini Vertical Systems

 

Compatible with SE300 MiniVE, SE260, and the SE250 Series Vertical Electrophoresis Systems.

 

Precision machined from Teflon®, which is highly resistant to acids, bases, and all commonly used buffer systems. An important benefit of Teflon® combs, compared to other types, is that they are easily removed while maintaining gel integrity. They are lightweight and virtually unbreakable when used with reasonable care. Some combs have microtiter spacing for use with multi-channel pipettes. (See Specifications.)

 

Standard Combs come attached to a standard back, which produces maximum well depths of 25 mm, except for the 28-well combs, which produce well depths of 15 mm.

  • 9- and 18-well Standard Combs have microtiter spacing for use with multichannel pipettes.
  • Preparative Combs have adjustable comb backs (10, 15, and 25 mm depth) and form 1 large preparative well plus 1 or 2 small reference wells.

Glow-Writer Pen

Glow Writeris a fine-point phosphorescent ink marking pen for making experimental notations and other markings on chemiluminescent and radioisotope-labeled substrate materials (e.g., transfer membranes, dried gels, genomic and proteomic matrices, etc.) being analyzed by X-ray film autography or electronic imaging. The unique marker delivers a phosphor-containing ink through a fine point porous nib. Before exposure to X-ray film, the phosphorescent writing is excited by room light. A phosphor ink having an optimum concentration of phosphor and a relatively short afterglow halflife (approximately 2-3 minutes) has been selected so that upon exposure to X-ray film,autographic exposures of almost any duration will be easily readable on the film. The fine point nib is easily replaceable if it dries out.

Fine-Point Phosphorescent Marking Pen for Laboratory Autography

  • Fine Point Nib- Provides fine writing and greater information density
  • Specially Designed- Ideal glow intensity and afterglow duration helps prevent over-andunder exposure
  • No Ink Clogs- Low ink viscosity and porous nib prevents ink from clogging

Western Blot Boxes

  • The perfect box for every blot
  • Reduce antibody usage
  • The hinged Lid minimizes evaporation
  • For halves, wholes, strips, or minis

 

No matter what size your Western blot is, there's a box that fits it perfectly. With boxes that are correctly matched to common blot sizes, you can fit more blots on shakers/rockers while keeping reagent and antibody usage to an absolute minimum. Additionally, all corners are formed at 90° angles and the bottom surface is uniformly flat, further reducing consumption of costly reagents and antibodies (for example, popular mini gels require only about 4 mL).


At a price that makes them truly disposable, all sizes are engineered from crystal clear polystyrene. The exception is our opaque black boxes (except WBB7BK and WBB15BK), which protect light-sensitive samples. All sizes are also equipped with an easy-to-open hinged lid that reduces evaporation.
