CD19 is present in both benign and malignant B-cells and is considered to be the most reliable surface marker of this lineage over a wide range of maturational stages. In normal lymphoid tissue, CD19 is observed in germinal centers, in mantle zone cells, and in scattered cells of the inter-follicular areas. Anti-CD19 exhibits an overall immunoreactivity pattern similar to those of the antibodies against CD20 and CD22. However, in contrast to CD20, expression of CD19 is continuous throughout B-cell development and through terminal differentiation of B-cells into plasma cells. Anti-CD19 positivity is seen in the vast majority of B-cell neoplasms commonly at a lower intensity than normal B-cell counterparts. Plasma cell neoplasms are nearly always negative, as are T-cell neoplasms.<\/p>\n<p>Primary antibodies are available purified, or with a selection of fluorescent CF\u00ae Dyes and other labels. CF\u00ae Dyes offer exceptional brightness and photostability. Note: Conjugates of blue fluorescent dyes like CF\u00ae405S and CF\u00ae405M are not recommended for detecting low abundance targets, because blue dyes have lower fluorescence and can give higher non-specific background than other dye colors.<\/p>\n<div style=\"margin:18px 0 4px;padding:11px 14px;background:#fdf4f4;border:1px solid #e6bdbd;border-left:3px solid #c41e3a;border-radius:4px;font-size:13px;line-height:1.55;color:#3a3a3a;\"><strong style=\"color:#8a1524;\">For Research Use Only (RUO).<\/strong> This product is sold strictly for laboratory research use only. <strong>Not for human or veterinary consumption, therapeutic, or diagnostic use.<\/strong> Any pharmacological, therapeutic, cosmetic, or biological effects described above are provided as research context only and do not represent intended or approved uses of this product.<\/div>\n","protected":false},"excerpt":{"rendered":"<p>CD19 is a transmembrane glycoprotein that contains two extracellular immunoglobulin-like domains.
