No matter what your western blot is, there's a box that fits it perfectly. With boxes that are correctly matched to common blot use, 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 4Ml. Many boxes are also available in light-blocking opaque black for light sensitive samples.
