Ephrin-A3/EFNA3 Protein, Mouse (HEK293, His)

Customer Review

Based on 1 Customer Validation

Ephrin-A3/EFNA3 Protein, a GPI-bound ligand, interacts with Eph receptors, playing a critical role in neuronal, vascular, and epithelial development. It binds adjacent Eph receptors, initiating bidirectional signaling. Ephrin-A3/EFNA3 also activates EPHA8, contributing to its regulatory functions in migration, repulsion, and adhesion. Ephrin-A3/EFNA3 Protein, Mouse (HEK293, His) is the recombinant mouse-derived Ephrin-A3/EFNA3 protein, expressed by HEK293 , with C-His labeled tag.

Description

Ephrin-A3/EFNA3 Protein, a GPI-bound ligand, interacts with Eph receptors, playing a critical role in neuronal, vascular, and epithelial development. It binds adjacent Eph receptors, initiating bidirectional signaling. Ephrin-A3/EFNA3 also activates EPHA8, contributing to its regulatory functions in migration, repulsion, and adhesion. Ephrin-A3/EFNA3 Protein, Mouse (HEK293, His) is the recombinant mouse-derived Ephrin-A3/EFNA3 protein, expressed by HEK293 , with C-His labeled tag.

Background

Ephrin-A3/EFNA3 Protein is a cell surface GPI-bound ligand that plays a critical role in neuronal, vascular, and epithelial development by interacting with Eph receptors, a family of receptor tyrosine kinases involved in migration, repulsion, and adhesion. It binds promiscuously to Eph receptors on adjacent cells, initiating contact-dependent bidirectional signaling. The receptor's downstream signaling is known as forward signaling, while the ephrin ligand's downstream signaling is referred to as reverse signaling. Ephrin-A3/EFNA3 also interacts with EPHA8 and activates this receptor, further contributing to its regulatory functions.

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

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.
