  • require a minimum of 40uL (is a conservative measurement to account for any dead volume during pipetting and to circumvent any evaporation that could occur during shipment. However, if volume is limited, we may also be able to start the assay with 20uL of sample volume. Upon completion of analysis, the remaining sample volume can be returned to you upon request.)

- Olink Flex is a customizable made-to-order product that enables the selection and combination of up to 21 biomarkers into one biomarker panel.
- Mix and match from ~200 inflammation-focused protein biomarkers.
- 15 to 21 assays per panel; 40 samples per kit
- Readout in absolute quantification in NPX
- We can also use pre-designed panel which include 25 inflammatory biomarkers
- Minimal sample volume
- Use only 1 uL of blood
- Fully validated protein biomarkers
- Production process follows the same strict procedure as all our products. See data results for each biomarker here.

The best approach is to screen the rat CSF with the Olink target 48-panel and then take the larger ones interested in to a custom flex panel (all the 48-panel targets are available for the clinical flex panel as well)
I'm getting a quote for N=50 rat CSF samples — if you know exactly which targets you're interested in, they can check the homology for us (the panel is for mouse, not rat; but homology is generally good). That said they will get us a quote for the kits only — we'll have to figure out the worst ourselves; but I prefer BioRgly for the inhouse.
We can use https://insight.olink.com/ to check that our candidate targets are compatible in the multi-plex (85% of targets are compatible)
Olink representative thought we might have one, but she wasn't sure;
sensitive, but not validated, only for mouse — so homology is a problem, low detectability even in TBI rat.

It is most effective for people who experience disabling tremors, wearing-off spells and medication-induced dyskinesias, with studies showing benefits lasting at least five years. That said, it is not a cure and it does not slow PD progression. It is also not right for every person with PD. It is not thought to improve speech or swallow issues, thinking problems or gait freezing.
