产品名称

Hypocretin-1 (human, rat, mouse)

产品介绍

Orexin A (human, rat, mouse) (Hypocretin-1 (human, rat, mouse)) 是一种 33 氨基酸兴奋性神经肽，参与多种中枢和外周过程。Orexin A (human, rat, mouse) 是一种特异性、高亲和力的 G 蛋白偶联受体OX1R激动剂，在调节摄食行为中起重要作用。Orexin A (human, rat, mouse) 是一种有效的抗伤害和抗痛觉过敏的药物。

生物活性

Orexin A (human, rat, mouse) (Hypocretin-1 (human, rat, mouse)), a 33 amino acid excitatory neuropeptide, orchestrates diverse central and peripheral processes. Orexin A (human, rat, mouse) is a specific, high-affinity agonist for G-protein-coupled receptorOX1R. Orexin A (human, rat, mouse) has a role in the regulation of feeding behavior. Orexin A (human, rat, mouse) is an effective anti-nociceptive and anti-hyperalgesic agent in mice and rats^[1]^[2].

IC₅₀& Target

OX₁Receptor

体外研究
(In Vitro)

Orexin A (human, rat, mouse) has high affinity for OX1R, with 38 nM IC₅₀and 34 nM EC₅₀values in the the [Ca^2﹢]i transient assay^[1].

体内研究
(In Vivo)

Orexin A (human, rat, mouse) (3-30 mg/kg; i.v.; 5 min pre-test) significantly increases the latency to response at 10 and 30 mg/kg i.v. when given 5 min pre-test from 24.8±2.0 s in vehicle-treated mice to 35.0±3.7 s and 45.7±4.5 s, respectively^[2].
Orexin A (human, rat, mouse) (3, 10 and 30 mg/kg; i.v.) was given immediately before phenylp-quinone (PPQ) and increases the latency to the first PPQ-induced constriction from 357.4±35.2 s in vehicle-treated mice to 500.3±31.2 s at 10 mg/kg and 594.5±5.5 s at 30 mg/kg^[2].

Animal Model:	Female mice (mouse carrageenan-induced thermal hyperalgesia test)^[2]
Dosage:	3, 10 and 30 mg/kg
Administration:	i.v.; 5 min pre-test
Result:	Significantly increased the latency to response at 10 and 30 mg/kg.

Peptide Solubility and Storage Guidelines:

1. Calculate the length of the peptide.

2. Calculate the overall charge of the entire peptide according to the following table:

	Contents	Assign value
Acidic amino acid	Asp (D), Glu (E), and the C-terminal -COOH.	-1
Basic amino acid	Arg (R), Lys (K), His (H), and the N-terminal -NH₂	+1
Neutral amino acid	Gly (G), Ala (A), Leu (L), Ile (I), Val (V), Cys (C), Met (M), Thr (T), Ser (S), Phe (F), Tyr (Y), Trp (W), Pro (P), Asn (N), Gln (Q)	0

3. Recommended solution:

Overall charge of peptide	Details
Negative (<0)	1. Try to dissolve the peptide in water first. 2. If water fails, add NH₄OH (<50 μL). 3. If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide.
Positive (>0)	1. Try to dissolve the peptide in water first. 2. If water fails, try dissolving the peptide in a 10%-30% acetic acid solution. 3. If the peptide still does not dissolve, try dissolving the peptide in a small amount of DMSO.
Zero (=0)	1. Try to dissolve the peptide in organic solvent (acetonitrile, methanol, etc.) first. 2. For very hydrophobic peptides, try dissolving the peptide in a small amount of DMSO, and then dilute the solution with water to the desired concentration.
