The availability of rapid and quantitative titration assays for retroviral vectors is important, especially in the context of clinical applications. In this report, we describe a novel assay to ...

Two vectors close vectorA vector quantity has both direction and magnitude (size). are parallel if they have the same (or opposite) directions. Their magnitude can be different. In the image to the ...

Last month, we saw how you can use vectors to define complex circuits and determine current. This month, we'll show you how to use vector diagrams and some simple math to calculate neutral currents in ...
