The purity of recombinant mLCN2 was determined by SDS-PAGE of 6 µg reduced (+) and non-reduced (-) recombinant mLCN2 and staining overnight with Coomassie Blue.Learn more about how we get our images
The viability of BAF3 cells treated with increasing amounts of mLCN2 was assessed. After 48 hr treatment with mLCN2, cells were incubated with a tetrazolium salt and the OD450-OD650 was determined.Learn more about how we get our images
Recombinant mouse LCN2 (mLCN2) Gln21-Asn200 (Accession #P11672) was expressed in human 293 cells at Cell Signaling Technology.
>98% as determined by SDS-PAGE of 6 μg reduced (+) and non-reduced (-) recombinant mLCN2 All lots are greater than 98% pure.
Recombinant mLCN2 contains no "tags" and the nonglycosylated protein has a calculated MW of 20,874. DTT-reduced and non-reduced proteins migrate as 24 kDa polypeptides.
The bioactivity of mLCN2 was determined in a BAF3 cell viability assay. The ED50 of each lot is between 0.5-4 µg/ml.
Less than 0.01 ng endotoxin/1 μg mLCN2.
With carrier: A 0.22 μm filtered solution of 0.33 mg/ml mLCN2 in 20 mM Tris, pH 8.0 containing 150 mM NaCl and 20 μg BSA per 1 μg mLCN2. Carrier free: A 0.22 μm filtered solution of 0.33 mg/ml mLCN2 in 20 mM Tris, pH 8.0 containing 150 mM NaCl.
Stable in lyophilized state at 4°C for 1 year after receipt. Sterile stock solutions reconstituted with carrier protein are stable at 4°C for 2 months and at -20°C for 6 months. Avoid repeated freeze-thaw cycles. Maintain sterility. Storage at -20°C should be in a manual defrost freezer.
Lipocalin-2, a member of the lipocalin family of proteins, was originally identified as a gelatinase-associated component of neutrophil secretory granules (1). Lipocalin-2 is involved in innate immunity, iron homeostasis, and apoptosis. Lipocalin-2 limits bacterial growth by binding to bacterial siderophores and sequestering iron (2-4). In mammalian cells, iron-loaded lipocalin-2 binds to its receptor, 24p3R, and is internalized, thereby releasing iron and increasing the intracellular iron concentration (5). Conversely, iron-free lipocalin-2 promotes apoptosis (5). Lipocalin-2 is also expressed in adipose tissue and promotes insulin resistance in cultured mouse adipocytes (6).
