製品の詳細Rabbit polyclonal to Lipocalin-2 / NGAL
特異性A customer has submitted a positive Abreview for rat samples in IHC. However, customers have experienced problems with rat samples and this is likely due to the low homology between the immunogen and the rat protein (30%). Some batches of this antibody may work in rat, but this is not batch tested.

機能Iron-trafficking protein involved in multiple processes such as apoptosis, innate immunity and renal development. Binds iron through association with 2,5-dihydroxybenzoic acid (2,5-DHBA), a siderophore that shares structural similarities with bacterial enterobactin, and delivers or removes iron from the cell, depending on the context. Iron-bound form (holo-24p3) is internalized following binding to the SLC22A17 (24p3R) receptor, leading to release of iron and subsequent increase of intracellular iron concentration. In contrast, association of the iron-free form (apo-24p3) with the SLC22A17 (24p3R) receptor is followed by association with an intracellular siderophore, iron chelation and iron transfer to the extracellular medium, thereby reducing intracellular iron concentration. Involved in apoptosis due to interleukin-3 (IL3) deprivation: iron-loaded form increases intracellular iron concentration without promoting apoptosis, while iron-free form decreases intracellular iron levels, inducing expression of the proapoptotic protein BCL2L11/BIM, resulting in apoptosis. Involved in innate immunity, possibly by sequestrating iron, leading to limit bacterial growth.
組織特異性Expressed in bone marrow and in tissues that are prone to exposure to microorganism. High expression is found in bone marrow as well as in uterus, prostate, salivary gland, stomach, appendix, colon, trachea and lung. Not found in the small intestine or peripheral blood leukocytes.
配列類似性Belongs to the calycin superfamily. Lipocalin family.
細胞内局在Secreted. Upon binding to the SLC22A17 (24p3R) receptor, it is internalized.

Anti-Lipocalin-2 / NGAL antibody (ab41105) at 1 µg/ml + Human colon tissue lysate - total protein (ab30051) at 30 µg
Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/10000 dilution
Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 23 kDa
Observed band size: 21 kDa why is the actual band size different from the predicted?
Additional bands at: 25 kDa, 70 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 12 minutes
ICC/IF image of ab41105 stained human Hek293 cells. The cells were methanol fixed (10 min), permabilised in 0.1% PBS-Tween (20 min) and incubated with the antibody (ab41105, 5µg/ml) for 1h at room temperature. 1%BSA / 10% normal goat serum / 0.3M glycine was used to block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue).
ab41105 staining Lipocalin-2 / NGAL in human lung tissue by Immunohistochemistry (Formalin/PFA-fixed paraffin embedded sections). Tissue underwent fixation in formaldehyde, heat mediated antigen retrieval in Citrate buffer pH6.0 and blocking for 15 minutes at 20°C (5 minutes peroxidase block and 10 minutes protein blocks). The primary antibody was diluted 1/250 or 1/1000 and incubated with sample for 45 minutes at 20°C. A HRP-conjugated goat polyclonal to rabbit IgG was used undiluted as the secondary.
