Immunogen

E. coli-expressed recombinant human IFN-γ

Formulation

0.2 ?m filtered in phosphate-buffered solution, pH 7.2, containing no preservative. Endotoxin level is <0.01 EU/?g of the protein (<0.001 ng/?g of the protein) as determined by the LAL test.

Preparation

The Ultra-LEAF? (Low Endotoxin, Azide-Free) antibody was purified by affinity chromatography.

Concentration

The antibody is bottled at the concentration indicated on the vial, typically between 2 mg/mL and 3 mg/mL. Older lots may have also been bottled at 1 mg/mL. To obtain lot-specific concentration, please enter the lot number in our Concentration and Expiration Lookup or Certificate of Analysis online tools.

Storage & Handling

The antibody solution should be stored undiluted between 2°C and 8°C. This Ultra-LEAF? solution contains no preservative; handle under aseptic conditions.

Application

ICFC - Quality tested
FC, Neut - Reported in the literature, not verified in house

Recommended Usage

Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 ?g per million cells in 100 ?l volume. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

Flow Cytometry²: The fluorochrome-labeled B27 antibody is useful for intracellular immunofluorescent staining and flow cytometric analysis to identify IFN-? -producing cells within mixed cell populations. For intracellular cytokine staining protocol, please visit www.biolegend.com and click on the support section.
Neutralization^1,3,6,7: The Ultra-LEAF? Purified antibody (Endotoxin <0.01 EU/?g, Azide-Free, 0.2 ?m filtered) is recommended for neutralization of human IFN-? bioactivity (Cat. No. 506531).
