Editorial policy
How our lab guides are written, sourced, dated and corrected.
What the guides are for
Our lab guides explain common methods, such as ELISA, western blot, qPCR and DNA and RNA extraction, so researchers can choose reagents and solve problems. They are general outlines. Your kit manual and your institution's safety rules take priority over anything written here.
How we source them
Each guide lists the published work behind it, linked at the end of the page: peer-reviewed papers and reference manuals. Every citation is checked against PubMed or the publisher's record before it is added. Where methods vary between kits or laboratories, we say so instead of giving one number as the rule.
What we will not publish
We do not invent statistics, prices, stock levels, processing times, reviews, authors or credentials. Named targets and products in a guide are examples, not a stock list. Availability is confirmed per quote.
Dates and updates
A guide's Updated date and a range's Last reviewed date change only when the content materially changes, such as a correction or a new section.
Research use
Reagents are supplied for research use unless stated otherwise. Nothing on this site is medical advice or a diagnostic instruction.
Photographs
Photographs on this site are licensed stock images chosen to illustrate the methods discussed. They do not show our own staff, premises or products.
Corrections
If you find an error, email info@bestqualitygood.com with the page and the source. We check it and correct the page if it is wrong.
