Immunogen

COS-7-expressed, recombinant mouse IL-6

Formulation

0.2 µm filtered in phosphate-buffered solution, pH 7.2, containing no preservative.

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 and expiration, please enter the lot number in our Certificate of Analysis online tool.

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

ELISA Capture - Quality tested
CyTOF® - Verified
ELISPOT Capture, Neut, IHC-F - Reported in the literature, not verified in house

Recommended Usage

Each lot of this antibody is quality control tested by ELISA assay. For ELISA applications, a concentration range of 0.5 – 2.0 µg/mL is recommended. To obtain a linear standard curve, serial dilutions of mouse IL-6 recombinant protein ranging from 500 to 8 pg/mL are recommended for each ELISA plate. For ELISPOT applications, a concentration range of 4.0 - 8.0 µg/mL is recommended. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

ELISA Capture^1-3,11 or ELISPOT Capture^4,5: The purified MP5-20F3 antibody is useful as the capture antibody in a sandwich ELISA or ELISPOT assay, when used in conjunction with the biotinylated MP5-32C11 antibody (Cat. No. 504602) as the detecting antibody and recombinant mouse IL-6 (Cat. No. 575709) as the standard. The Ultra-LEAF™ purified antibody is suggested for ELISPOT capture.

Flow Cytometry: The fluorochrome-labeled MP5-20F3 antibody is useful for intracellular immunofluorescent staining and flow cytometric analysis to identify IL-6 -producing cells within mixed cell populations. For intracellular cytokine staining protocol, please visit www.biolegend.com and click on the support section.

Neutralization^1-2,8-10: The Ultra-LEAF™ purified antibody (Endotoxin <0.1 EU/µg, Azide-Free, 0.2 µm filtered) is recommended for neutralization of mouse IL-6 bioactivity in vivo and in vitro (Cat. Nos. 504511-504516).

Additional reported applications (for relevant formats of this clone) include: In Vivo Capture⁷, and immunohistochemical staining (paraformaldehyde-fixed/saponin-treated⁶, and acetone-fixed frozen tissue sections^{13, 14}).

Note: For testing mouse IL-6 in serum, plasma or supernatant, BioLegend's ELISA Max™ Sets (Cat. Nos. 431301 to 431306) are specially developed and recommended.
