Background

The Tachykinin-3 protein, belonging to the family of active peptides known as tachykinins, demonstrates multifaceted physiological effects, including the excitation of neurons, induction of behavioral responses, potent vasodilation, secretion stimulation, and the contraction of various smooth muscles. Additionally, Tachykinin-3 emerges as a pivotal central regulator with a critical role in governing gonadal function. The intricate interplay of these diverse actions underscores the significance of Tachykinin-3 in orchestrating physiological responses and maintaining homeostasis, particularly in the regulation of reproductive processes.

Product Properties

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.22 μm filtered solution of 20 mM Tris-HCl, pH 8.0.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
