Rat anti Human Interleukin-4 antibody, clone MP4-25D2
recognizes human Interleukin-4 (IL-4), also known as B-cell stimulatory factor 1, Binetrakin, Pitrakinra or Lymphocyte stimulatory factor 1. Interleukin-4 is a 153 amino acid ~17kDa cytokine involved in the activation of B cells, macrophages and monocytes (UniProt: P05112
Polymorphisms in the IL-4 gene are associated with susceptibility to, and outcome of ischemic stroke (Marousi et al. 2011
Rat anti Human Interleukin-4 antibody, clone MP4-25D2 is reported to neutralize IL-4 activity (Abrams et al. 1992
and Carvalho et al. 1994

Applications of IL-4 antibody
|Flow Cytometry 1
|Immunohistology - Frozen
- 1Membrane permeabilization is required for this application. Bio-Rad recommend the use of Leucoperm™ (Product Code BUF09) for this purpose.
Where this antibody has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the antibody for use in their own system using appropriate negative/positive controls.
- Flow Cytometry
- Use 10ul of the suggested working dilution to label 1x106 cells in 100ul.
