PR1MA Rapid Coomassie Stain

Chemical Formula: C5H10O5

Solubility: Water

Storage Temp: Room Temperature

This unique Coomassie Blue based formulation features a special dye that is absorbed by protein bands instead of the gel matrix. This eliminates the need for destaining and offers enhanced sensitivity and sharper resolution of bands. Protein bands can be detected within 10 minutes. Maximum intensification may require incubation up to 40 minutes. Offers greater convenience and sensitivity than conventional stains. Compatible with silver staining. Rapid Coomassie stain uses a simple two-step procedure. Stain is designed to detect as little as 7.9ng of protein within one hour of electrophoresis.

Supplied as 20X concentrated solution.

Shelf life is approximately 18 months at room temperature.

Shipping Weight: 0.3 lbs

Shipping Dimensions: 2.00 x 4.00 x 2.00
  • Appearance: Dark Blue Color
  • Concentration: 20X
  • Solubility: Suitable for use in staining protein in polyacrylamide gels

Gel Crusher Spin Column

 

Rapid Gel Fragmentation for DNA Recovery.

 

Gel Crusher Spin Columns provide a fast, efficient, and consistent method for gel fragmentation, replacing traditional crush-and-soak or manual gel breaker steps. Designed with 600 uM filtration pores, these columns enable quick and uniform fragmentation of agarose or acrylamide gel slices, saving time and increasing DNA recovery yields.

 

Ideal for workflows in molecular cloning, PCR cleanup, restriction digests, DNA sequencing, and labeling protocols, the Gel Crusher simplifies the preparation of gel fragments for downstream purification and elution steps.

 

Simply insert the Gel Crusher column into a 2 mL microcentrifuge tube, add your pre-cut gel slice (prepared using a gel cutter or razor blade), and centrifuge at max speed (~15,000 x g) for 5 minutes. The gel will be forced through the 600 uM pores, producing small, uniform fragments that can be easily pipetted using wide-bore tips into NaCl or other solutions.

 

This process creates a fine slurry that enhances elution efficiency and improves access to the target nucleic acids, significantly reducing incubation and processing time.

 

Key Features

  • Efficiently breaks gel slices into uniform fragments
  • Eliminates manual crush-and-soak steps
  • Increases DNA yield and recovery efficiency
  • Fits standard 2 mL microcentrifuge tubes
  • Compatible with standard benchtop centrifuges (up to 15,000 x g)
  • 600 uM pore size ideal for agarose or acrylamide gels
  • Simplifies downstream processes: elution, filtration, incubation
  • For use in PCR, cloning, digestion, sequencing, and more 

Reversible Racks

  • 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.

  • Low molecular weight proteins
  • Typically used for chemiluminescence
  • Not ideal for stripping
  • Excellent binding properties

 

Quantity: 10 membranes each

Azure PVDF Membranes

 

Pre-cut PVDF membranes for Western blotting applications

Ideal for chemiluminescent and colorimetric Western blotting. Pre-cut to save you time in the lab. These low-fluorescence PVDF membranes reduce background noise and nonspecific protein binding for improved sensitivity. Available in three different pre-cut sizes.

 

Quantity: 10 membranes per package

 

Features

Low-fluorescence PVDF membranes reduce background noise for improved sensitivity. PVDF (polyvinylidene difluoride) membranes are commonly used for immunoblotting techniques, like Western blots. During the blotting process, samples are transferred from the protein gel onto a PVDF membrane by electroblotting. From there they can be used for protein sequencing.

  • High binding capacity is great for low-expressing proteins
  • Typically used for fluorescence
  • High protein retention for stripping and reprobing
