Description

Introduction
The interleukin 4 receptor binds to IL13, which may contribute to many overlapping functions of this cytokine and IL13. STAT6, a signal transducer and activator of transcription, has been shown to play a central role in mediating the immune regulatory signal of this cytokine. This gene, IL3, IL5, IL13, and CSF2 form a cytokine gene cluster on chromosome 5q, with this gene particularly close to IL13. IL4, IL13 and IL5 are found to be regulated coordinately by several long-range regulatory elements in an over 120 kilobase range on the chromosome.

BP000157-CYT-097: Recombinant Human IL-4 Protein, HEK

Source: HEK-derived.
Predicted molecular mass: 14-19 kDa.
The activity was determined by the dose dependent stimulation of the proliferation of human TF-1 cells (human erythroleukemic indicator cell line) and is typically 0.1-0.5 ug/ml.
Purity: > 95% as obsereved by SDS-PAGE.
Formulation: The IL4 was lyophilized from 1 ug/ml in 1xPBS.
Reconstitution: It is recommended to reconstitute the lyophilized IL-4 in sterile water not less than 100 ug/ml, which can then be further diluted to other aqueous solutions.

Shipping: The product is shipped with ice pack. Upon receipt, store it immediately at the temperature recommended below.
Stability & Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
12 months from date of receipt, -20 to -70°C as supplied.
1 month, 2 to 8°C under sterile conditions after reconstitution.
3 months, -20 to -70°C under sterile conditions after reconstitution.
