It is overexpressed in many cancers, acting as a negative regulator of T cell immune responses, thereby aiding in immune evasion. Its expression is associated with poor outcomes and survival times in patients. Through various studies, B7-H3 has been linked to other functions associated with tumor progression, such as angiogenesis, metastasis, and exosomal activity. B7-H3 can also be released in soluble form (sB7-H3) into the tumor microenvironment, where it has been implicated in increased migration and invasion of cancer cells. Due to its relative absence in normal tissues and its multifaceted effects on tumor cells, B7-H3 is an attractive target for immunotherapy treatments.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cspan class=\"bhp-cat-pill\"\u003eImmunotherapy\u003c\/span\u003e\n\u003cp\u003eB7 homolog 3 protein (B7-H3) CHO Cell line is a recombinant clonal stable CHO cell line expressing full length human B7-H3 protein, also known as cluster of differentiation 276 (CD276, B7H3; B7RP-2; 4Ig-B7-H3). Surface expression of B7-H3 was confirmed by flow cytometry. Each stable clonal cell line was selected for High, Medium, or Low levels of B7-H3 expression to mimic different B7-H3 expression levels in various cancer types.\u003c\/p\u003e\n\u003ch2\u003eProduct Specifications\u003c\/h2\u003e\n\u003ctable class=\"bhp-spec-table\"\u003e\n\u003ctr\u003e\n\u003cth\u003eHost Cell Line\u003c\/th\u003e\n\u003ctd\u003eCHO-K1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHost Species\u003c\/th\u003e\n\u003ctd\u003eHamster, epithelial-like cells, adherent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTransfection Method\u003c\/th\u003e\n\u003ctd\u003eLipofectamine 2000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSupplied As\u003c\/th\u003e\n\u003ctd\u003eEach vial contains 2 x 10\u003csup\u003e6\u003c\/sup\u003e cells in 1 ml of cell freezing medium (BPS Bioscience #79796)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHarmonized Tariff Code\u003c\/th\u003e\n\u003ctd\u003e3002-5900\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eQuality Control \u0026amp; Validation\u003c\/h2\u003e\n\u003cspan class=\"bhp-qc-badge\"\u003e✓ Mycoplasma-Tested\u003c\/span\u003e\n\u003cp\u003eThe cell line has been screened to confirm the absence of Mycoplasma species.\u003c\/p\u003e\n\u003ch2\u003eSafety \u0026amp; Handling\u003c\/h2\u003e\n\u003cdiv class=\"bhp-warning-box\"\u003e\n\u003cp style=\"margin:0 0 4px\"\u003e⚠ Avoid freeze\/thaw cycles.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2\u003eRegulatory Information\u003c\/h2\u003e\n\u003cdiv class=\"bhp-regulatory-row\"\u003e\n\u003cdiv class=\"bhp-reg-item\"\u003e\n\u003cstrong\u003eLicense Required\u003c\/strong\u003eYes\u003c\/div\u003e\n\u003cdiv class=\"bhp-reg-item\"\u003e\n\u003cstrong\u003eLiving Modified Organism\u003c\/strong\u003eYes\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2\u003eLicense Disclosure\u003c\/h2\u003e\n\u003cdiv class=\"bhp-license-box\"\u003eVisit bpsbioscience.com\/license for the label license and other key information about this product.
