Recombinant Human Interleukin-4 protein (IL4) (Active) | CSB-AP001711HU | Cusabio

Protein Description: Full Length of Mature Protein

Alternative Name (s) : IL-4, BSF-1, Binetrakin, Lymphocyte stimulatory factor 1, Pitrakinra

Gene Names: IL4

Research Areas: Immunology

Species: Homo sapiens (Human)

Source: E.Coli

Tag Info: Tag-Free

Expression Region: 25-153aa


Biological Activity: Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using human TF-1 cells is less than 0.2 ng/ml, corresponding to a specific activity of > 5.0 × 106 IU/mg.

MW: 15.0 kDa

Purity: >98% as determined by SDS-PAGE and HPLC.

Endotoxin: Less than 1.0 EU/µg as determined by LAL method.

Relevance: Participates in at least several B-cell activation processes as well as of other cell types. It is a costimulator of DNA-synthesis. It induces the expression of class II MHC molecules on resting B-cells. It enhances both secretion and cell surface expression of IgE and IgG1. It also regulates the expression of the low affinity Fc receptor for IgE (CD23) on both lymphocytes and monocytes.

Tissue Specificity:

Paythway: Jak-STATsignalingpathway

Form: Lyophilized powder

Buffer: Lyophilized from a 0.2 µm filtered PBS, pH 7.4

Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
