CNTN5/Contactin-5 Protein, Human (HEK293, His)

Customer Review

Based on 1 Customer Validation

CNTN5/Contactin-5 protein mediates cell surface interactions in nervous system development, promoting neurite outgrowth in cerebral cortical neurons but not in hippocampal neurons. It is involved in auditory system neuronal activity and interacts with PTPRG, potentially regulating neuronal functions and connectivity. CNTN5/Contactin-5 Protein, Human (HEK293, His) is the recombinant human-derived CNTN5/Contactin-5 protein, expressed by HEK293 , with C-His labeled tag.

Biological Activity

Description

CNTN5/Contactin-5 protein mediates cell surface interactions in nervous system development, promoting neurite outgrowth in cerebral cortical neurons but not in hippocampal neurons. It is involved in auditory system neuronal activity and interacts with PTPRG, potentially regulating neuronal functions and connectivity. CNTN5/Contactin-5 Protein, Human (HEK293, His) is the recombinant human-derived CNTN5/Contactin-5 protein, expressed by HEK293 , with C-His labeled tag.

Background

Contactin-5 (CNTN5) plays a crucial role in mediating cell surface interactions during nervous system development. While it exhibits neurite outgrowth-promoting activity in cerebral cortical neurons, it does not exert the same effect in hippocampal neurons. CNTN5 is implicated in neuronal activity within the auditory system, highlighting its potential role in sensory processes. Furthermore, it interacts with protein tyrosine phosphatase receptor gamma (PTPRG), suggesting a molecular partnership that may contribute to the regulation of neuronal functions and connectivity.

Product Properties

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.

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
