IL4 antibody

• Catalog Number: orb345142
• Category: Antibodies
• Description: IL4 antibody
• Species/Host: Rabbit
• Clonality: Polyclonal
• Tested applications: ELISA, WB
• Reactivity: Human
• Isotype: IgG
• Immunogen: This purified antibody was prepared from whole rabbit serum produced by repeated immunizations with full length recombinant human IL-4 protein.
• Concentration: 1.0 mg/mL
• Dilution range: ELISA: 1:10,000, WB: 1:1,000
• Form/Appearance: Lyophilized
• Purity: This product is an IgG fraction antibody purified from monospecific antiserum by a multi-step process which includes delipidation, salt fractionation and ion exchange chromatography followed by extensive dialysis against the buffer stated above. This purified antibody has been heated to 56°C for 30 minutes. In ELISA and other immunoreactive assays, this antibody will recognize both native and recombinant human IL-4 in cell supernatants and certain body fluids. A control of similarly diluted normal rabbit IgG is recommended.
• Conjugation: Unconjugated
• UniProt ID: P05112
• NCBI: NP_000580.1
• Storage: Store anti-IL-4 antibody at 4° C prior to restoration. For extended storage aliquot contents and freeze at -20° C or below. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4° C as an undiluted liquid. Dilute only prior to immediate use.
• Buffer/Preservatives: None
• Alternative names: rabbit anti-IL-4 antibody, rabbit anti-interleukin
• Note: For research use only
• Application notes: This purified antibody has been tested in western blotting. Reactivity is also expected in ELISA, neutralizations, radioimmunoassay and immunohistochemistry. The endotoxin content is estimated to be < 10 pg/µl by the LAL method. By western blot a band approximately 15 kDa in size corresponding to native human IL-4 protein is expected in the appropriate cell lysate or extract. Specific conditions for reactivity should be optimized by the end user.
• Expiration Date: 12 months from date of receipt.

Biorbyt's anti-Human IL-4 antibody shows detection of a band ~15 kDa in size corresponding to recombinant human IL-4. The identity of the faint higher molecular weight band may represent a homodimer. Molecular weight markers are also shown (left). After transfer, the membrane was blocked overnight with 3% BSA in TBS followed by reaction with primary antibody at a 1:1000 dilution. Detection occurred using peroxidase conjugated anti-Rabbit IgG (p/n orb347654) secondary antibody diluted 1:40000 in blocking buffer (p/n orb348637) for 30 min at RT followed by reaction with FemtoMax™ chemiluminescent substrate.
