Optical Density - an overview | ScienceDirect Topics

Helen Louise Brown, in Reference Module in Biomedical Sciences, 2021. Optical density. Optical density (OD) is a method of quantifying microbial growth in relation to the turbidity of an inoculum, i.e., its optical density. An assumption is made that the number of microbes within any suspension is directly proportional to the turbidity of the culture and as such, dilution to a set …

May 09, 2008 Centrifugation for laboratory tests is not as critical as for blood components, but protocols should state centrifuge speed in the appropriate g, and if this cannot be done, then ‘centrifuge’ or ‘gentle centrifugation’ as the case may be, could be used. Standard operating procedures should be in place and should always be followed.

Ribosome - protein factory - Rs Science

The name of subunits is based on their sedimentation rate, meaning how fast they can be settled down when a mixture of cell lysis was span in a centrifuge. This rate is measured in Svedberg units (S) rather than size. This is why subunits’ names do not add up: for example, bacterial 70S ribosomes are made of a large 50S and a small 30S ...
