US Patent No: 5360720

Method of preparing human conjunctival mast cells for mast cell stabilization assays

---

Abstract

---

By allowing the mast cell enriched population of human conjunctival tissue cells to incubate for a minimum of about forty (40) hours post enzymatic digestion, the treatment window between spontaneous histamine release and anti-human IgE stimulated histamine release is increased. Culturing the human conjunctival tissue mast cells decreases the spontaneous release of histamine and increases the anti-IgE stimulated histamine release, greater than ten fold over spontaneous, at time points over forty (40) hours. This treatment window is sufficient to detect a compound's stabilizing or anti-allergic activity.
