Simplify Your Western: Six Simple Steps

Western blotting is viewed as the gold standard for protein detection in molecular biology research. It is used to identify proteins within a cell or tissue lysate. Antibodies against your protein(s) of interest, bind to specific epitopes to identify the target protein within a lysate. Due to the high specificity of the binding, multiple target proteins can be identified on one membrane. Secondary antibodies then bind to your primary antibodies and when exposed to a substrate react allowing for the visualization of the corresponding protein band.

Who wants to spend all that time in the dark?

We have removed the need for you to spend time in the dark room.
Let your blot develop before your eyes, right there on your bench!

No need to spend time in the dark room

Signal Develops In Front Of Your Eyes

The WESTERNVIEW® Detection Kits for Western Blot analysis quickly and clearly reveal bands on the transfer membrane without the need for specialized equipment.

The most common method of visualization still seen today is via a chemiluminescent reaction. This involves spending time in a tight dark room, with a timer and a list of exposure times, which are mostly chosen based on educated guesswork.

  • A simple solution for real-time results – no film developer or fluorescent reader required or time in the dark room.
  • High sensitivity – quickly visualize your bands with minimal overexposure risk and with no visible background.
  • Convenient and easy to use – includes secondary antibody and all reagents necessary to visualize your bands.

Antibodies for Loading Controls

Find the right loading control to ensure proper interpretation of your Western blots. The sample type will help you determine which target to use for your loading control. Typically, loading controls are housekeeping proteins expressed at high and consistent levels.

Loading controls are used to:
  • Check for equal transfer across membrane
  • Ensure even loading between lanes
  • Normalize and quantify your data

Prestained Protein Ladder

Protein ladder for use with protein gel electrophoresis

  • 3 μL or 5 μL per loading for clear visualization during electrophoresis on 15-well or 10-well mini-gel, respectively
  • Three color protein standard with 13 prestained proteins
  • Apply more for thicker (>1.5 mm) or larger gel

Our Protein ladder is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins. The ladder is supplied in gel loading buffer and is ready to use. Do not heat, dilute or add reducing agent before loading.

Proteins are covalently coupled with a blue chromophore except for two reference bands (one green and one red band at 25 kDa and 75 kDa respectively) when separated on SDS-PAGE (Trisglycine buffer).
