Anti-Mouse/Human IL-5 – Purified in vivo GOLD™ Functional Grade
Pricing & Details
Partially-purified T cell clone supernatant
≥ 2.0 mg/ml
< 1.0 EU/mg as determined by the LAL method
≥95% monomer by analytical SEC
>95% by SDS Page
This monoclonal antibody is aseptically packaged and formulated in 0.01 M phosphate buffered saline (150 mM NaCl) PBS pH 7.2 - 7.4 with no carrier protein, potassium, calcium or preservatives added. Due to inherent biochemical properties of antibodies, certain products may be prone to precipitation over time. Precipitation may be removed by aseptic centrifugation and/or filtration.
Functional grade preclinical antibodies are manufactured in an animal free facility using only In vitro protein free cell culture techniques and are purified by a multi-step process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates.
Storage and Handling
This Low Endotoxin Functional Formulation, GOLD Antibody is stable when stored at 2-8°C. For long term storage aseptically aliquot in working volumes without diluting and store at –80°C. Avoid Repeated Freeze Thaw Cycles.

Applications and Recommended Usage?
Quality Tested by Leinco
FC: The suggested concentration for this TRFK5 antibody for staining cells in flow cytometry is ≤ 1.0 μg per 106 cells in a volume of 100 μl. Titration of the reagent is recommended for optimal performance for each application. NOTE: A fluorochrome-conjugated TRFK51 antibody would be useful for intracellular staining and flow cytometric analysis to identify IL-5-producing cells within mixed cell populations.
ELISA:This purified TRFK5 antibody is useful as a capture antibody for a sandwich ELISA assay. A suitable detection antibody would be a biotinylated clone TRFK4 antibody for mouse IL-5, or used in conjunction with biotinylated JES1-5A10 antibody.
Other Applications Reported In Literature ?
NeutralizationThis Purified In vivo GOLD™ Functional Grade antibody (Endotoxin <1.0 EU/mg) is recommended for neutralization of human IL-5 bioactivity. CyTOF®
Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change.

Mast cells, T cells, eosinophils
IL-5 is a 26 kD TH2 cytokine and a homodimeric glycoprotein that is part of the hematopoietic family. IL-5 stimulates B cell growth as well as increases Ig secretion. It is the main factor that promotes the terminal differentiation of eosinophil progenitors and enhances the effector capacity of mature eosinophils. IL-5 is a major regulator of eosinophil accumulation in tissues. In fact, in Hodgkin lymphoma, the characteristically observed eosinophilia is suspected to result from an increased production of IL-5. IL-5 may also be the cause of several allergic diseases including asthma, where it is thought that eosinophils have a significant role in the disease pathology. There are several mAbs currently in use that target IL-5 for the treatment of severe eosinophilic asthma.
