WebFixation is a process that helps to lock proteins in place on cells you plan to analyze. Because fixation can alter epitopes, this can create problems for antibody staining if samples are fixed prior to staining with antibodies.

In this setup, NbPSD95 only stained mitochondria when the expressed GFP fusion protein comprised PDZ-domains derived from PSD95, thereby corroborating the specificity of NbPSD95 for its target.
WebWhen generating paraffin-embedded tissue samples, the tissue must be fixed before embedding in paraffin. Fixation is achieved by perfusion or immersion immediately following dissection. The process typically takes 4 - 24 hours (fixation for longer than 24 hours is not recommended as it may lead to overfixation, which may mask the antigen).
