I am working with some colleagues on historic FFPE sections from multiple sites that have been (unknowingly) cut onto different types of glass slide.
We have used Thermo SuperFrost Plus (J1800AMNZ) and Thermo Polysine coated (J2800AMNZ). Both are positively charged.
I know that positively charged and non-charged slides may display different staining properties; I wonder if anyone has any experience with different charged coatings and whether this is something we need to be mindful of regarding quantitative analysis?
