Protein Isolation How to Choose Membrane Protein Isolation Kits
Plasma membrane (PM) proteins play a critical role in a variety of physiological and pathological processes. Signal transduction, molecular transport and cell-cell interactions are all mediated by PM proteins. PM proteins include a variety of important proteins such as neurotransmitter receptors, G-proteins, carriers, voltage-gated ion channels, CD antigens and many drug targets. The detec...
Artifacts in IHC: the usual suspects - part I
After a few intense days of meticulous tissue washes and antibody incubations my staining is finally ready. I am staring at it down the microscope. I enjoy what I see: a dark brown color exactly where I expect to see it! Am I good or what? I give myself a figurative pat on the back and an imaginary high five. Excited and proud, I call my supervisor who glares intently at it and t...
Calibration and Performance Tracking of Flow Cytometer SpheroTechnical Notes #8
The SPHERO™ Calibration Particles are versatile, stable, economical and convenient to use. These particles contain a mixture of fluorochrome which are spectrally similar to many of the fluorochromes used in flow cytometry. As a result, they are used for routine alignment, day-to-day performance verification and long term performance tracking of several channels of flow cytometers in one run. These part...
In vivo magnetofection How to use OZ Biosciences' in vivo magnetofection™
The main problems currently associated with systemic gene vector administration (gene therapy) include biodistribution of gene vector throughout the body, the lack of specificity towards a pathological site (bioavailability at the target site), the necessity of a large dose to achieve high local concentration, non-specific toxicity, inactivation of vectors due to undesired interactions with components of the in vivo mi...
