Detects human FCRL4/FcRH4 in direct ELISAs and Western blots. In direct ELISAs and Western blots, less than 2% cross‑reactivity with recombinant human (rh) IRTA2, rhIRTA3, rhIRTA4, and rhIRTA5 is observed.
Polyclonal Goat IgG
Mouse myeloma cell line NS0-derived recombinant human FCRL4/FcRH4 Gln16-Asp385 Accession # Q96PJ5
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
Detection of Human FCRL4/FcRH4 by Western Blot.
Western blot shows lysates of RPMI 8226 human multiple myeloma cell line and K562 human chronic myelogenous leukemia cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human FCRL4/FcRH4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2426) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for FCRL4/FcRH4 at approximately 58 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

FcRH4, also known as IRTA1 (immunoglobulin superfamily receptor translocation associated 1), is a member of the Ig superfamily. It shares sequence homology with the classical Fc receptors. FcRH4 is preferentially expressed in B cells and contains three potential ITIM motifs in its extracellular domain. The gene for FcRH4 is localized to the human chromosome Iq 21‑23 region, a hotspot for translocation events.
