The total protein is measured using the Biuret procedure with bovine albumin as the standard; F/P ratio is calculated using absorbance at 491.5nm. Antibody titer of the IgG fraction is standardized with an in-house control by immunoelectrophoresis. The IgG fraction is tested for purity and specificity at 40 mg/mL using immunoelectrophoresis. The product is mostly goat IgG; no trace of albumin is detected.
Antibody and FITC are conjugated under defined conditions to obtain the specified molar ratio (3-6mol/mol). Conjugated protein is purified by gel filtration. The product is dialyzed into 0.02M sodium phosphate, 0.14M sodium chloride, pH 7.3, with 0.05% sodium azide, adjusted to standard titer, filtered through a 0.22 μm filter, vialed, and lyophilized.
FITC-Conjugated Goat IgG Fraction to Anti-Human Complement C4 is used as a reagent in immunofluorescence assays (IFA), cell staining (fluorescent microscopy and cell sorting), tissue staining, and blot immunostaining.
Product is the lyophilized powder of fluorescein-5-isothiocyanate (FITC "Isomer I")-conjugated goat IgG fraction to human complement C4 and buffer salts.
