IL-13Ra1, His, Human

Human IL-13, No Tag immobilized on CM5 Chip can bind IL-13Ra1, His, Human, His Tag with an affinity constant of 0.55 μM as determined in SPR assay (Biacore T200).

IL-13Ra1, His, Human

Two type 1 membrane proteins belonging to the hemopoietin receptor family have been cloned and shown to bind IL-13 with differing affinities. The lower affinity IL-13 binding protein, previously designated IL-13 R alpha, IL-13 R alpha ' or NR4, is now referred to as IL-13 R alpha 1. The high-affinity IL-13 binding protein, previously also designated IL-13 R or IL-13 R alpha ', is now referred to as IL-13 R alpha 2.
