The pH values of all buffers are temperature and concentration dependent. For Tris buffers, pH increases about 0.03 unit per °C decrease in temperature, and decreases 0.03-0.05 unit per ten-fold dilution.
For precise applications, use a carefully calibrated pH meter with a glass/calomel combination electrode.

Lysosomes are dynamic organelles that serve as regulatory hubs in cellular homeostasis. Changes in lysosome morphology, composition, and turnover are typically linked to disease. These characteristics make enrichment protocols based on biophysical parameters challenging. However, organelle enrichment methods are essential...

10x Blocking Buffer Protocol

Membrane-based blotting applications that employ enzyme conjugates to generate colorimetric or chemiluminescent signal require the use of an added blocking step to decrease the signal generated by non-specific binding.

RNAi In Situ

In Situ Hybridization of Whole-Mount Mouse Embryos with RNA Probes: Hybridization, Washes, and Histochemistry. This is a protocol describing how to perform in situ hybridization on whole mouse embryos. Here we describe the hybridization procedure, and the localization of the DIG-labeled RNA using a conjugate of anti-DIG Fab antibody and calf intestinal alkaline phosphatase. Enzyme activity of the reporter is detected by a color reaction, resulting in the formation of a water-insoluble purple/blue precipitate. Manipulating the Mouse Embryo - Third Edition

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
