IL-4 antibody | MP4-25D2
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 asociated 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).
