||FUNCTION: Neuropeptides that play a significant role in the regulation of food intake and sleep-wakefulness, possibly by coordinating the complex behavioral and physiologic responses of these complementary homeostatic functions. A broader role in the homeostatic regulation of energy metabolism, autonomic function, hormonal balance and the regulation of body fluids, is also suggested. Orexin-A binds to both OX1R and OX2R with a high affinity, whereas orexin-B binds only to OX2R with a similar high affinity. SUBCELLULAR LOCATION: Endoplasmic reticulum; rough endoplasmic reticulum. Associated with perikaryal rough endoplasmic reticulum as well as cytoplasmic large granular vesicles at synapses. SIMILARITY: Belongs to the orexin family.

||A synthetic peptide (CRLYELLHGAGNHAAGILTL) as part of Bovine Orexin A (aa: 14-33) conjugated to KLH has been used as the immunogen.
||Orexin-A; Hypocretin-1; Hcrt1
||IHC. This is a superb antiserum for immunohistochemistry on Orexin A containing neurons exhibiting intense labelling of neurons with very low back ground. A dilution of 1:1000 to 1:2000 is recommended for this application. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.
||The specificity for this antiserum has been confirmed by immunohistochemistry on rat brain and the results reflect the current literature.
||This antibody is known to react with rat Orexin A.
||If you would like to use this product in another species other than those specified here, or to see the shared ID between the immunogen used here in different species and/or other molecules, simply copy the immunogen (from the Immunogen field) and paste it HERE and blast/format it. Note that, antisera raised against synthetic peptides are quite often very specific for that peptide ie, only one single amino acid difference may be enough to restrict the specificity to a particular molecule. Regardless, you can always contact us if you need assistance with this.
||Reconstitute in 100 µl of sterile water. Centrifuge to remove any insoluble material.
||Store lyophilized antibody at 2-8ºC. After reconstitution keep aliquots at -20ºC for a higher stability, and at 4ºC with an appropriate antibacterial agent. Glycerol (1:1) may be added for an additional stability. Avoid repetitive freeze/thaw cycles.
