Product Introduction:

vPairTM antibodies represent a pair of fully characterized antibodies that recognize two different regions of a target protein. The product is developed by Abiocode to address whether the signal observed truly represents the protein of interest, an often encountered issue in antibody-based assays. The use of a pair of fully characterized vPairTM antibodies in the same assay can validate signal specificity since vPairTM antibodies recognize two independent epitopes of the same protein. Different sets of vPairTM antibodies are developed at Abiocode to work with specific applications, including antibody arrays, Western blot, IP-Western, ChIP, IHC, and FACS.


Interleukin 4 (IL4) is a pleiotropic cytokine produced by activated T cells.  It participates in several B-cell activation processes as well as of other cell types.  It induces the expression of class II MHC molecules on resting B-cells.  IL4 is the ligand for interleukin 4 receptor which can also bind IL13.  IL4 is a costimulator of DNA-synthesis.  It enhances secretion and cell surface expression of IgE and IgG1.      

Other Names:

BCGF-1, BCGF1, BSF1, IL-4, MGC79402

Source and Purity:

Rabbit polyclonal antibodies were produced by immunizing animals with a GST-fusion protein containing either the N-terminal region [IL4 (N) (R0071-1)] or the C-terminal region [IL4 (C) (R0071-2)] of human IL4. Antibodies were purified by affinity purification using immunogen. 

Storage Buffer and Condition:

Supplied in 1 x PBS (pH 7.4), 40% Glycerol, 0.01% NaN3. Store at -20 °C. Stable for 6 months from date of receipt.

Species Specificity:


Recommended Conditions: 

WB: 1:1,000-1:5,000 (detect recombinant protein)

ELISA:  > 1:1,000- 1:10,000 (detect native recombinant protein in a direct ELISA assay). Suitable for using as ELISA capture or detection antibody.

*: The apparent protein size on WB may be different from the calculated M.W. due to modifications.
