Biological Activity

Description

ESAM protein promotes aggregation through a possible homophilic molecular interaction and interacts with MAGI1. ESAM Protein, Mouse (HEK293, His) is the recombinant mouse-derived ESAM protein, expressed by HEK293 , with C-His labeled tag.

Background

ESAM protein is capable of facilitating aggregation, likely through a homophilic molecular interaction. It has been observed to interact with MAGI1.

Verified Bioactivity

Measured by its ability to chemoattract Jurkat Human T lymphocyte leukemia cells. The ED50 for this effect is 137.6 ng/mL, corresponding to a specific activity is 7.267×103 U/mg.

MCE Validation Data

Product Properties

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.

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.

Shipping

Room temperature in continental US; may vary elsewhere.
