{"product_id":"nsj-v6091-100ug","title":"INSM1 Antibody \/ Insulinoma-associated 1, 100ug","description":"\u003cp\u003eInsulinoma-associated protein 1 (INSM1) is a zinc finger transcription factor encoded by the INSM1 gene that plays an important role in neuroendocrine cell differentiation during embryonic development. The protein functions as a transcriptional regulator controlling genes involved in neuroendocrine lineage specification and hormone producing cell maturation. INSM1 Antibody for IHC (clone MSVA-456R) recognizes the INSM1 protein and is designed specifically for immunohistochemistry detection of neuroendocrine cells and tumors in formalin-fixed, paraffin-embedded tissue sections.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;Immunohistochemistry is the primary method used to evaluate INSM1 expression in pathology and research studies because the protein exhibits a distinctive nuclear staining pattern. As a transcription factor, INSM1 localizes to the nucleus, producing clear nuclear HRP-DAB staining in positive cells while surrounding stromal and epithelial components remain largely negative. This nuclear signal provides a highly interpretable immunohistochemistry readout and allows investigators to readily identify neuroendocrine tumor cells within complex tissue architecture.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;In normal human tissues, INSM1 expression detected by immunohistochemistry is typically restricted to scattered neuroendocrine cells within epithelial organs. Nuclear staining may be observed in endocrine cells of the pancreas, bronchial neuroendocrine cells of the respiratory tract, and rare neuroendocrine cells of the gastrointestinal mucosa. Because these cells represent specialized hormone secreting lineages, immunohistochemistry detection of INSM1 provides a reliable method for identifying neuroendocrine differentiation in tissue sections.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;INSM1 immunohistochemistry has become widely used in the evaluation of neuroendocrine tumors. Strong nuclear staining is frequently observed in small cell lung carcinoma, pulmonary neuroendocrine tumors, Merkel cell carcinoma, and neuroendocrine tumors arising in the pancreas or gastrointestinal tract. In contrast, most conventional epithelial carcinomas and non neuroendocrine tissues demonstrate minimal or absent nuclear staining, allowing INSM1 immunohistochemistry to clearly highlight neuroendocrine tumor populations within histological specimens.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;Tissue microarray immunohistochemistry studies provide additional evidence of the highly selective staining pattern of INSM1. Analysis of large panels of normal and cancer tissues typically demonstrates strong nuclear staining in neuroendocrine tumor types while the majority of non neuroendocrine tissues remain negative. These tissue array data reinforce the value of INSM1 as a nuclear marker of neuroendocrine differentiation and support its use in immunohistochemistry-based tumor classification studies.\u0026lt;br\u0026gt;\u0026lt;br\u0026gt;INSM1 Antibody for IHC (clone MSVA-456R) is a recombinant rabbit monoclonal antibody developed to produce consistent nuclear staining in immunohistochemistry applications. When used on formalin-fixed tissue sections, staining typically appears as distinct nuclear HRP-DAB signal in neuroendocrine cells and tumors, enabling clear visualization of neuroendocrine differentiation in both individual tissue sections and large tissue microarray analyses.\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;\"\u003eV6091-100UG\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;\"\u003e100ug\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-456R\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): 1:75-1:150\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.
