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.

Related FAQs

Do you guarantee that your antibodies are totally pathogen free?

BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.

Does BioLegend test each Ultra-LEAF™ antibody by functional assay?

No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.

Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?

No, BioLegend does not test for pathogens in-house unless otherwise indicated.  However, we can recommend an outside vendor to perform this testing as needed.

Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?

We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
