我们明白。西部片的污点可能会让人头疼，我们当然也有过这样的经历。因此，请与我们分享您的丑陋污点，并获得一份惊喜！虽然我们不能告诉你是什么--那会破坏惊喜的气氛--但它会激发实验室的创造力。

We get it. Westerns can be a pain in the blot, and we’ve certainly made our share. So, share with us your ugly blots and receive a surprise! And while we can’t tell you what it is – that would spoil the surprise - except that it will spark creativity in the lab.

In Western blotting, blocking of unbound membrane sites is necessary to prevent non-specific binding of the antibodies which otherwise would lead to a high background on the blot. The traditional milk blocker can work well; however, inadvertent variations in its composition can lead to irreproducible results. Such variations include the milk’s concentration, fat content, solubility, detergent quality, and numerous other factors. Bløk reagents are a family of protein-free, noisecancelling reagents that reduce background for consistent, quality results. They are available in three room temperature-stable, ready-to-use formulations for Chemiluminescence and chromogenic detection, Fluorescence detection, and Phosphoprotein immunodetection. The protein-free nature of Bløk reagents allows for membranes to be stained with chromogenic reagents, such as Ponceau S or Coomassie™ blue, after blocking or immunodetection. Bløk reagents have been tested and validated for Western blot, dot blot, and ELISA applications.

There’s so much room for experimental variability in traditional immunodetection workflows. For your peace of mind – and ours – we designed the SNAP i.d.® 2.0 system to streamline your Western blot and immunohistochemistry experiments. The concept is simple: a vacuum-driven flow of blocking, antibody, and washing solutions reduces slide and membrane handling. That means a lot less shaking, dipping, pouring and waiting. And now you can process multiple blots and slides in parallel, so it’s easy to apply consistent conditions across experiments.
