Catalog # ML8741
Mouse Macrophage + LPS (18 hr)
Size 100 μl
Nitric oxide (NO) has a broad range of biological activities and is implicated in signaling pathways in phylogenetically diverse species. Nitric oxide synthases (NOS) are the enzymes responsible for synthesis of NO and several distinct NOS isoforms are produced from three distinct genes. The inducible form of NOS, iNOS (also designated NOS-II), is Ca2+ independent and is expressed in a broad range of cell types. This form of NOS is induced in macrophages and monocytes after stimulation with cytokines and exposure to microbial products, such as LPS.
Confluent cultures of mouse macrophage cells (J774A.1) were either left untreated (cat.# ML8731) or treated with LPS (1 μg/ml) for 18 hrs at 37°C (cat.# ML8741). Cells were lysed in 1% SDS, 1.0 mM sodium ortho-vanadate, 1 mM sodium fluoride, 10 mM Tris (pH 7.4) buffer. Protein concentration was determined using the BCA method (Pierce) before diluting to final concentration and buffer. The LPS treated lysate has significant induction of iNOS expression relative to the control cells as demonstrated using anti-iNOS antibodies (NM3981 and NP2131).
