{"product_id":"nsj-v6145-20ug","title":"CD22 Antibody \/ CD22 molecule, 20ug","description":"\u003cp\u003eCD22, also known as Siglec-2 and B-cell receptor CD22, is a B cell-restricted transmembrane glycoprotein encoded by the CD22 gene that functions as a critical regulator of B cell receptor signaling and immune tolerance. CD22 Antibody for IHC \/ CD22 Immunohistochemistry Antibody (clone MSVA-022R) is optimized for high-resolution detection of CD22 in formalin-fixed, paraffin-embedded tissues, enabling precise visualization of B cell populations within intact tissue architecture. CD22 expression is tightly restricted to mature B lymphocytes, including follicular and mantle zone B cells, making it a highly specific marker for identifying B cell lineage in immunohistochemistry studies.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;CD22 antibody, also referred to as Siglec-2 antibody or B-cell receptor CD22 antibody in the literature, is uniquely suited for tissue-based analysis where spatial context is essential. In immunohistochemistry, CD22 demonstrates a consistent membranous and cytoplasmic staining pattern that highlights B cell distribution within lymphoid organs such as lymph node, tonsil, and spleen. This staining pattern allows clear delineation of germinal centers and surrounding B cell zones, supporting detailed evaluation of lymphoid architecture in both normal and reactive tissues.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;The strength of CD22 Antibody for IHC is particularly evident in tissue microarray analysis, where parallel staining across a wide range of normal tissues reinforces its lineage specificity. In tissue microarray panels, CD22 staining is consistently confined to lymphoid compartments, with strong signal observed in B cell-rich regions and minimal to absent staining in epithelial, stromal, and parenchymal tissues. This high contrast between positive and negative compartments enhances interpretability and makes CD22 a reliable marker for identifying lymphoid infiltrates within complex tissue environments.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;In cancer tissue microarray studies, CD22 expression remains robust in B cell-derived malignancies, including diffuse large B-cell lymphoma, follicular lymphoma, and other non-Hodgkin lymphomas. Immunohistochemistry staining highlights neoplastic B cells with clear membranous and cytoplasmic localization, allowing distinction from surrounding non-neoplastic cells. Importantly, most non-B cell tumors lack CD22 expression, further supporting its use as a lineage-specific marker in diagnostic and research immunohistochemistry applications.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;The recombinant rabbit monoclonal format of this CD22 antibody, clone MSVA-022R, supports consistent staining intensity and low background across tissue microarray platforms, where reproducibility is critical for comparative analysis. This consistency is particularly valuable in large-scale tissue microarray studies that require uniform performance across diverse tissue types and experimental conditions.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;Due to its restricted expression profile, strong performance in FFPE tissues, and compatibility with tissue microarray workflows, CD22 remains an essential marker for immunohistochemistry-based investigation of B cell biology, tumor classification, and immune cell distribution. This CD22 antibody enables detailed tissue-level analysis, supporting studies of lymphoid organization, malignant B cell identification, and immune infiltration within normal and diseased tissues.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;This antibody is part of the broader \u0026lt;a href=..\/cd22-antibody-b-cell-marker.html\u0026gt;CD22 antibody\u0026lt;\/a\u0026gt; collection for studying B cell markers, immune regulation, and hematologic malignancies.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;This antibody is also part of a broader collection of \u0026lt;a href='\/ihc-antibodies-tissue-microarray-validated.html'\u0026gt;IHC antibodies validated by tissue microarray analysis\u0026lt;\/a\u0026gt;, supporting consistent staining across normal and cancer tissues.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable style=\"width:100%;border-collapse:collapse;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;vertical-align:top;padding:6px;border-bottom:1px solid #eee;\"\u003eCatalog No\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003eV6145-20UG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;vertical-align:top;padding:6px;border-bottom:1px solid #eee;\"\u003eFamily\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003ePrimary antibody\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;vertical-align:top;padding:6px;border-bottom:1px solid #eee;\"\u003eQty\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003e20ug\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;vertical-align:top;padding:6px;border-bottom:1px solid #eee;\"\u003eFormulation\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003eAntibody in 1X PBS with 0.05% BSA, 0.05% sodium azide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;vertical-align:top;padding:6px;border-bottom:1px solid #eee;\"\u003eFormat\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003ePurified\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;vertical-align:top;padding:6px;border-bottom:1px solid #eee;\"\u003eClone\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003eMSVA-022R\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;vertical-align:top;padding:6px;border-bottom:1px solid #eee;\"\u003eHost Animal\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003eRabbit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;vertical-align:top;padding:6px;border-bottom:1px solid #eee;\"\u003eClonality\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003eRecombinant Rabbit Monoclonal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;vertical-align:top;padding:6px;border-bottom:1px solid #eee;\"\u003eIsotype\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003eRabbit IgG, kappa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;vertical-align:top;padding:6px;border-bottom:1px solid #eee;\"\u003eSpecies Reactivity\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003eHuman\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;vertical-align:top;padding:6px;border-bottom:1px solid #eee;\"\u003eApplication\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003eIHC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;vertical-align:top;padding:6px;border-bottom:1px solid #eee;\"\u003eApplication Details\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003eImmunohistochemistry (FFPE): 1:100-1:200\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;vertical-align:top;padding:6px;border-bottom:1px solid #eee;\"\u003eApplication Note\u003c\/th\u003e\n\u003ctd style=\"padding:6px;border-bottom:1px solid #eee;\"\u003e1.
