General description

IL-5 (interleukin 5) is a Th2 (T helper 2) cytokine that is predominantly produced by T lymphocytes, and to a lower extent by mast cells, type 2 innate lymphoid (ILC2) cells, and eosinophils.
Recombinant murine IL-5 is a 26.2kDa disulfide-linked homodimeric protein containing two 113 amino acid chains.

Biochem/physiol Actions

IL-5 (interleukin 5) was initially identified as a stimulant of antibody production by activated B cells. It has recently been shown to be a key factor in eosinophil differentiation and proliferation. It is also implicated in the pathogenesis of asthma, atopy, hypereosinophilic syndromes, and parasitic infections. In distal lung, IL-5 recruits eosinophils and modulates inflammatory or immune cells in the microenvironment, thus, promoting lung metastasis in cancer.

Physical form

Lyophilized from 10 mM Sodium Phosphate, pH 7.5.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.

The human eosinophil differentiation factor (EDF) gene was cloned from a genomic library in lambda phage EMBL3A by using a murine EDF cDNA clone as a probe. The DNA sequence of a 3.2-kilobase BamHI fragment spanning the gene was determined....

Activation-induced deaminase (AID) is a DNA-mutating enzyme that mediates class-switch recombination as well as somatic hypermutation of antibody genes in B cells. Due to off-target activity, AID is implicated in lymphoma development by introducing genome-wide DNA damage and initiating chromosomal...

Complement is implicated in asthma pathogenesis, but its mechanism of action in this disease remains incompletely understood. In this study, we investigated the role of properdin (P), a positive alternative pathway complement regulator, in allergen-induced airway inflammation. Allergen challenge stimulated...
