生物活性

Orexin B, human (TFA) is an endogenous agonist at Orexin receptor with Kis of 420 and 36 nM for OX1 and OX2, respectively.

IC50 & Target

Ki: 420 nM (OX1), 36 nM (OX2)[1].
体外研究
(In Vitro)

Orexin B is derived by proteolytic amino acid precursor, prepro-orexin, which is encoded by a gene localized to chromosome 17q21 in humans. In radioligand binding studies, Orexin B has a higher affinity for the OX2 receptor[1].
Human Orexin B has two amino acid substitutions when compared with the rodent sequence. OX2 receptor is indeed a high-affinity receptor for human orexin B, with an IC50 of 36 nM in the binding assay and an EC50 of 60 nM in the [Ca2+]i transient assay. Human Orexin B has significantly lower affinity for the human OX1: the calculated IC50 in the competitive binding assay and the EC50 in the [Ca2+]i transient assay are 420 nM and 2500 nM for human orexin-B, respectively[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Orexin B, human TFA 相关抗体:
体内研究
(In Vivo)

Human Orexin B significantly augments food intake; at the 2 hr time point, 5- and 12-fold stimulation of food consumption is observed by 3 nM and 30 nM orexin-B, respectively[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male Wistar rats (180-200 g)[2].
Dosage: 3 nM and 30 nM.
Administration: Administered in a 5 mL bolus through a catheter placed in the left lateral ventricle in early light phase.
Result: Significantly augmented food intake.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
