Finding the annual return on investment (ROI) for assets at OP bank

Sun, 09 Jan 2022 00:00:00 +0000

I am a customer of the Finnish OP bank . Like many other people, I had more leftover money than normally during the coronavirus pandemic. And like many others, I also invested some of that money into the stock market. I do not follow the stock market, but at the end of the year, I want to know how my investments performed: I want to know the annual return on investment (ROI) or the IRR (internal rate of return) for my whole portfolio and also for my individual stocks.

HiLoad 26/60 Superdex pg gel filtration chromatography column performance

The most common protein purification technique that we use is gel filtration (also called size exclusion chromatography). In gel filtration, proteins are separated by their size (or more correctly by their “Stokes radius”, which is largely determined by their size and shape). For gel filtration of large protein amounts, we bought GE Healthcare’s HiLoad 26/60 Superdex 200 prep grade about 9 years ago (the 26/60 has been replaced by HiLoad 26/600, but both are almost identical). With this column you can very cleanly separate two proteins that have a size difference of 100%. Therefore it is suitable to separate monomeric from dimeric versions of the same protein. The columns “expiry date” was 2012-03. Our experience is that under proper handling, such a column can easily reach a life span of 10 to 15 years (we don’t use it very often, we store it in 20% ethanol, if we don’t need it for longer periods of time, we keep it at +4°C).
