what changed for me between week 90 and week 44
Long-ish post, sorry. tl;dr at the bottom. I have been tracking LC-MS against ApoB for 9 weeks because I could not find anyone who had. The correlation is weaker than I expected, which is itself mildly interesting given how confidently people link the two in here. Caveats up front: one person, one lab, one assay, no…
This is the correct method framing. Column and gradient are load-bearing fields.
Strongly agree. Largest single impurity tells a different story than total purity.
Slight fix: the number was 97.6, not 98.1. Decimal point, but a fairly consequential one.
chromatogram or it did not happen
Not to be pedantic but gradient and method development are being used interchangeably and they are not interchangeable in real life.
Rodent data is rodent data. Dose scaling is not linear and the models tell you what to investigate, not what to expect.
