Serpin I2 Protein, Human (HEK293, His)

Serpin I2 Protein, is a member of the serpin (serine protease inhibitor) superfamily. Serpin I2 (pancpin) is an inhibitory serpin targeting pancreatic elastase and chymotrypsin. Serpin I2 is downregulated in pancreatic and breast cancer, and associated with acinar cell apoptosis and pancreatic insufficiency when absent in mice. Serpin I2 is associated with refractive error and has the potential for further investigations of the genetic susceptibility to myopia research. Serpin I2 Protein, Human (HEK293, His) is the recombinant human-derived Serpin I2 protein, expressed by HEK293 , with C-6*His labeled tag.

Description

Serpin I2 Protein, is a member of the serpin (serine protease inhibitor) superfamily. Serpin I2 (pancpin) is an inhibitory serpin targeting pancreatic elastase and chymotrypsin. Serpin I2 is downregulated in pancreatic and breast cancer, and associated with acinar cell apoptosis and pancreatic insufficiency when absent in mice. Serpin I2 is associated with refractive error and has the potential for further investigations of the genetic susceptibility to myopia research[1][2]. Serpin I2 Protein, Human (HEK293, His) is the recombinant human-derived Serpin I2 protein, expressed by HEK293 , with C-6*His labeled tag.

Background

Serpin I2 contains a Met-Ser within the reactive centre loop which is also found in anti-trypsin. Serpin I2 deficiency in mice caused pancreatic insufficiency and acinar cell apoptosis, resulting in a stunted pequeno phenotype with immune cell defects and reduced life span[1].
Serpin I2 polymorphisms increase susceptibility to refractive error. Serpin I2 is a promising candidate for further investigations of the genetic susceptibility to myopia. Serpin I2 is involved in acinar cells of the pancreas and may be important to control glucose metabolism[2].

Product Properties

Appearance

Lyophilized powder.

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
