holographic origin of life

... and we give the exact food, then if these organisms are just random chemical reactions, their lifespan could be predicted as a result of multiple linear regression. The dependent variable y (or else the lifespan) would be: y=a+a1x1+a2x2+…….aνxν+aωxω+ε where ε is the error variable and x1,x2…xν ...

Problem with the normalization of PCR Ct values

You should not divide the CTs, because they are not linear. You have to subtract them and the difference will tell you how many times more copies there was.

Western Blot

... is, otherwise known as its molecular weight. When extracts are prepared from a cell, detergents can be used to make the proteins unfold into the linear chain of amino acids. Using a detergent such as sodium dodecyl sulfate (SDS) makes proteins unfold and gives them a net negative charge that ...

SDS-PAGE gel and Rf values

... weight markers in lane one of the gel that I attached. When I do this and graph the Rf values against the molecular weight my graph is not linear. I marked in red where I am measuring from. Can someone please tell me what I am doing wrong?

Which is the best calculation for growth?

... of the experiment (Nt). Because of my experimental setup, I can not count cells in-between. If I could, I would determine a growth rate by doing a linear regression of a log-plot of my cell-nr over time and the slope is then my growth rate. However, with two points only, a regression is senseless. ...
