I am currently adsorbing proteins to an aluminum hydroxide gel. By adding a carbomer (polymer of acrylic acid cross-linked with allyl sucrose), I achieve a somewhat synergistic formulation. Shortly after adding the carbomer, a granular precipitate forms that adheres to glass. Questions: 1) What is this precipitate?; 2) Will my adsorbed protein release from the aluminum hydroxide after carbomer addition?; 3) Is there possible long-term instability of this mixture? Thank you!
