The Development of a Cocktail of Microglia and GFAP For Easy Diagnosis - Anisha Bhasin B.S, Sarah Holguin, MBA. B.S, Joe Vargas, M.S

Microglia and GFAP are distinct neural markers, typically used separately to diagnose the degree of neurological infection and injury. Microglia, a glial cell, is used in the immune response of the central nervous system. GFAP is an astrocyte marker; astrocytes provide structural support and make up the blood-brain barrier. Using the two in conjugation with one another would prove to be an efficient diagnostic tool. A cocktail was constructed with optimal titration to observe the two markers in unison. In clinical usage, it will provide an efficient diagnosis of chronic inflammatory conditions of the central nervous system. The staining was conducted in IHC and fluorescence to compare morphology and count. Due to anatomical similarities, there tends to be morphological confusion between microglia and GFAP. However, when stained in conjunction with one another, notable differences can allow for easy distinction. This is why a cocktail run with a dual staining technique would be a superior diagnostic tool in comparison to testing the two markers independently.
