Looking forward to reading it.

I’m glad. A lot of successful IP-MS assays we have heavily relies on internal antibodies.

I run it at 0.8 uL/min with 50C heating and the pressure is at 600 bar. I also commonly use it at 0.4uL/min, off the top of my head it is at around 350-400 bar. 1000 bar if I run it at 1.3 uL/min.

Recently got a TQ absolute. Will report back once we start running samples with Ionkey. We mostly run plasma and CSF samples.

Thyroglobulin is a famous one. To be honest, there are not many. Unlike ELISA where GMP quality labs produce kits to ensure assay maintenance, I think it’s challenging to maintain a mass spec protein biomarker in the clinic with the labs being the developer and manufacturers at the same time.

Rapizyme is pretty awesome. Highly pure, heat resistant.

Rapizyme maybe able to replace out trypsin+ProteaseMax to be honest if you want it simple.
