MP Biomedicals - 0855510 - Fluorescein-Conjugated Goat IgG F(ab')2 Fragment to Mouse Complement C3, 2mL

ITEM #: 5123451
Product is the lyophilized powder of fluorescein-5-isothiocyanate (FITC "Isomer I")-conjugated goat F(ab')2 fragment to mouse complement C3 and buffer salts.
Applications
Fluorescein-Conjugated Goat F(ab')2 Fragment to Mouse Complement C3 is intended for laboratory use to qualitatively stain sections of frozen tissue, and is also suitable for use as a reagent in immunofluorescence assays (IFA), cell staining (fluorescent microscopy and cell sorting), tissue staining, and blot immunostaining. F(ab')2 fragments are recommended for staining of cells or tissues which contain Fc receptors.
Recommended Use
Reconstitute product with 2.0 mL of deionized or distilled water. Gentle swirling may be used to speed rehydration. Avoid vigorous shaking of the reconstituted material.
Preparation Method
Antibody and FITC are conjugated under defined conditions to obtain the specified molar ratio (3-6 mol/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.
Analysis Note
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 by equivalence-point precipitation. The F(ab')2 fragments are tested for purity and specificity at a minimum of 20 mg/mL using immunoelectrophoresis; No trace of albumin, whole molecule IgG or Fc is detected. Antibody activity to other serum proteins is not present.
