{"product_id":"biolegend-648820","title":"Biolegend, 648820, Purified anti-MRP-14 (S100A9) Antibody, 25μg","description":"\u003cp\u003eThe S100A8\/A9 complex has been shown to play a role in calcium-dependent activation and exhibits antibacterial, antifungal, immunomodulatory, and anti-proliferative effects. It also functions as a chemoattractant for neutrophils and serves as an endogenous activator of Toll-like receptor 4 (TLR4). S100A9 has been identified as a marker of CD14⁺ HLA-DR⁻\/low myeloid-derived suppressor cells (MDSCs).\u003cbr\u003e\n25μg\u003cbr\u003e\nVerified Reactivity: Human\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Mouse\u003cbr\u003e\nImmunogen: Recombinant protein of human MRP-14 (S100A9)\u003cbr\u003e\nFormulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide\u003cbr\u003e\nPreparation: The antibody was purified by affinity chromatography.\u003cbr\u003e\nConcentration: 0.5 mg\/mL\u003cbr\u003e\nStorage \u0026amp; Handling: The antibody solution should be stored undiluted between 2°C and 8°C.\u003cbr\u003e\nApplication: IHC-P - Quality tested ICC, ICFC - Verified\u003cbr\u003e\nRecommended Usage: Each lot of this antibody is quality control tested by formalin-fixed paraffin-embedded immunohistochemical staining. For immunohistochemistry, a concentration range of 1.0 - 10.0 µg\/mL is suggested. For immunocytochemistry, a concentration range of 1.25 - 10.0 μg\/mL is recommended. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per million cells in 100 µL volume. It is recommended that the reagent be titrated for optimal performance for each application.\u003cbr\u003e\nAdditional Product Notes: For use in immunohistochemistry on formalin-fixed paraffin-embedded tissue (IHC-P), it is recommended to perform antigen retrieval using either Citrate Buffer, 10X (Cat. No. 420902) or Tris-EDTA pH 9.0 Antigen Retrieval Buffer (10X) (Cat. No. 422704). For use in immunocytochemistry (ICC), it is recommended to fix\/permeabilize with Fixation buffer (Cat. No. 420801) with 100% ice-cold methanol. For use in intracellular flow cytometry (ICFC), it is recommended to fix\/permeabilize with Cyto-Fast™ Fix\/Perm Buffer Set (Cat. No. 426803). Fixation\/permeabilization with either True-Phos™ Perm Buffer (Cat. No. 425401) or True-Nuclear™ Transcription Factor Buffer Set (Cat. No. 424401) is not recommended.\u003cbr\u003e\nRRID: AB_3720530 (BioLegend Cat. No. 648820) AB_3720530 (BioLegend Cat.
