VMO1 Protein, Human (HEK293)

Customer Review

Based on 1 Customer Validation

Vitelline membrane outer layer protein 1 homolog (VMO1) is first characterized in the outer layer of the vitelline membrane of hen’s eggs, where VMO1is present together with lysozyme, VMO2, and ovomucin. VMO1 is a secreted protein and exerts important functions in inner ear and tear film, VMO1 may also interact with glycosylated proteins. VMO1 Protein, Human (HEK293) is the recombinant human-derived VMO1 protein, expressed by HEK293 , with tag free.

Background

Vitelline membrane outer layer protein 1 homolog (VMO1) is first characterized in the outer layer of the vitelline membrane of hen’s eggs, where VMO1is present together with lysozyme, VMO2, and ovomucin. Determination of the crystal structure of VMO1 revealed that VMO1 may interact with glycosylated proteins.VMO1 is a secreted protein and exerts important functions in inner ear and tear film[1].

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.

Shipping

Room temperature in continental US; may vary elsewhere.
