This monoclonal antibody is aseptically packaged and formulated in 0.01 M phosphate buffered saline (150 mM NaCl) PBS pH 7.2 - 7.4 with no carrier protein, potassium, calcium or preservatives added.
Functional grade preclinical antibodies are manufactured in an animal free facility using only In vitro protein free cell culture techniques and are purified by a multi-step process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates.
To protect mouse colonies from infection by pathogens and to assure that experimental preclinical data is not affected by such pathogens, all of Leinco’s Purified Functional PLATINUMTM antibodies are tested and guaranteed to be negative for all pathogens in the IDEXX IMPACT I Mouse Profile.
Storage and Handling
Functional grade preclinical antibodies may be stored sterile as received at 2-8°C for up to one month. For longer term storage, aseptically aliquot in working volumes without diluting and store at -80°C. Avoid Repeated Freeze Thaw Cycles.

Other Applications Reported In Literature ?
Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change.
Clone 50946 recognizes human FcRL5 within the first 3 Ig domains. Clone 50946 does not cross-react with FcRL4.
FcRL5 is expressed on mature B cells and plasma cells.
FcRL5 antibody, 509F6, recognizes Fc receptor-like 5 (FcRL5), also known as immunoglobulin superfamily receptor translocation associated 2 (IRTA2), Fc receptor homolog 5 (FcRH5), and BXMAS1. FcRL5 is a 106 kDa type I transmembrane glycoprotein containing 9 Ig-like extracellular domains, a cytoplasmic ITAM-like consensus sequence, and two cytoplasmic ITIM-like sequences1. FcRL5 is found on most mature B cells, with the highest levels on naive and memory B cells and plasma cells1,2. FcRL5 is an IgG receptor and binds to all IgG isotypes3, resulting in the inhibition of BCR signaling through the recruitment of SH2 domain-containing tyrosine phosphatase 1 (SHP-1) after tyrosine phosphorylation of its two ITIMs4. B cell malignancies, including multiple myeloma, chronic lymphocytic leukemia, mantle cell lymphoma, and hairy cell leukemia, often exhibit aberrant FCRL5 expression, indicating FcRL5 as a potential biomarker or therapeutic target5-7.
