I'm putting together a high school laboratory basics textbook with an Amazon equipment list. I think these are the cheapest "knockoff" Eppendorf tubes I can find. amzn.to/3Yqct4T

Has anyone tried these super cheap Amazon Pipetteman??...they have a pretty good lookin 2uL and 10uL for MALDI spotting ...I gotta give it a try amzn.to/4dipSjO

Copper conductive double sided tape on Amazon. Low priced alternative for anyone MALDI imaging non-conductive stuff. Didn't peel off even after spraying matrix and in/out of the Bruker Ultraflex ultra low vacuum! Good stuff! amzn.to/4blUcIK via @amazon

When you buy a real expensive new instrument, it would be nice if you had the option to attend instrument repair training similar to a service engineer. I love our service engineers but I would also prefer to have all the knowledge in my own brain.

My GC-MS trace looks like this? Anyone know what the problem could be? Is it a leak? Or a detector issue?

Favorite MALDI matrix for complex protein fingerprinting? Comment solvent ratios.

Is there a good multiplexed way to isolate exosomes from plasma for MALDI fingerprinting?

Tired of the same boring expensive lab notebooks - check out what I just did! I scanned an old worn lab notebook and turned it into a new one a.co/d/fR1OHih

What's the best software option for mapping K to C proteins xlinking with known linker mass and b&y ion calculator for mapping xlinked tryptic fragments?

ODD-ONE-OUT Chemical Structure Puzzles 2: Essential Medicine Edition is out! This time test your skills for spotting difference on @WHO Essential Medicines. Fun for all ages. a.co/d/b0JKQ4Z

Is MSDIAL the best place to download a huge metabolomics database...ESI(+)-MS/MS from standards+bio+in silico (16,995 unique compounds) includes everything right? Any other suggestions???

Does anyone have a good MZmine tutorial for Waters FastDDA data that includes compound ID with isotope pattern matching. Im very close...I just want to include isotope pattern scores but I cant figure out the isotope peak grouper.

I made another! Slightly Easier Puzzles this time and more educational. Spot the Difference in Protein Structures - Kids Edition: a.co/d/6t1LySO #amazonbooks

My new book is out on amazon! ODD-ONE-OUT Chemical Structure Puzzles: Toxins and Poisons Edition a.co/d/fSLs85U #Amazon #selfpublishing #Science #chemistry #puzzles

Try to spot the differences - the GFP on the right is missing 5 things a.co/d/3PiWGhk

Does anyone else calibrate like this? gravity fed calibration waters Xevo QTOF CsI youtube.com/shorts/uW18tmz0X… via @YouTube

Thiolized yeast is the GMO nobody is talking about. dIPA+ Lyase 👍👍

Using daltons makes me a biochemist?...analytical chemists getting no respect per usual.

Would you bother learning a new MS software tool if it came with a 6-month free evaluation license but an unknown yearly price tag afterwards. #TeamMassSpec

I see all these nextgen protein sequencing companies focusing on complex proteosomes....why not just sequence a recombinant protein first. Like can anyone even do that with a commercial chip based system...cause I'd buy one.
