The IgG-FITC concentration is approximately 1mg/ml in phosphate-buffered saline (PBS) containing 1 mg/ml bovine albumin and 0.1% sodium azide (w/v), pH 7.4. The incorporation of FITC is ≥ 3.0 moles fluorescein per mole IgG as determined spectrophotometrically. Total protein is 0.1 mg.

Host Animal: Sheep

Specificity: Prior to conjugation, no reaction was observed with normal human plasma using immunoelectrophoresis and immunodiffusion techniques.

Application: This product is suitable as a negative control in procedures where sheep antibodies are used.
