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

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.
