Log

Log

Formally, the number of times ten must be multiplied with itself to equal a certain number. For example: 100,000 is log 5 because it is equal to 10 x 10 x 10 x 10 x 10. Logs are used to measure changes in viral load (see). For example: a reduction in viral load from 100,000 to 1,000 copies/ml is a two log (or 99 percent) reduction. Note that a half log change is not a five-fold difference but a change of 3.16-fold (the square root of ten).

Oh,come on. If a kid or someone else in my household had posted that as a response, I'd have been instantly emailing a GROVELLING apology to DNLee explaining exactly how it had happened. Wouldn't you? If something as humiliating and offensive as that went out under my name, and it wasn't ...

SDS-PAGE gel and Rf values

You should measure from the very top of the gel. Did you plot it against log of MW?

Log paper

If is log paper what I think it is, you should have the actual numbers in there. Or you can calculate the log MW and put it on normal paper.
