Detects recombinant human PILR-beta in direct ELISAs and Western blots. In Western blots, approximately 10% cross reactivity with recombinant human PILR-alpha is observed and less than 5% cross-reactivity with recombinant mouse (rm) PILR-beta, rmPILR-alpha, and rmPILR-L is observed.

Paired immunoglobulin-like, type 2 receptor beta (PILR-beta ) is a type I transmembrane (TM) glycoprotein belonging to the Ig superfamily. It is the activating counterpart to the ITIM-bearing PILR-alpha inhibitory receptor. PILR-beta is expressed in a wide variety of hematopoietic cells, including NK cells, macrophages, dendritic cells and neutrophils. Mature human PILR-beta is a 208 amino acid (aa) protein with one V-type Ig-like extracellular domain, a truncated cytoplasmic tail, and a positively-charged residues in its TM domain that interacts with ITAM‑bearing adaptor molecules. Over aa 20-189, in their ECD, human PILR-beta and PILR-alpha share 82% aa sequence identity. The aa sequence of mouse PILR-beta ECD is only 43% identical to that of human PILR-beta ECD.
