pH of neutral collagen is approximately 9. The molecule is deionised and neutral. Normally, the iso electric point can be altered slightly by manufacturing process alterations. However, there is a patent you could look at for gelatine: https://www.freepatentsonline.com/2398004.html

Hi, wow, that was really helpful, thanks! Do you know of any papers or patents that alter the manufacturing process to therefore increase the isoelectric point of gelatin?

No but I will see if I can find. A lot would be personal knowledge/secrets of the industry of making gelatine.

Yeah...that'd be a lot of help because a couple of Google searches and reading through research papers hasn't been finding anything about being able to add adjust gelatin's isoelectric point! Thanks 😅
