Preparation Note
Contains no animal-derived components or impurities, and is manufactured by transient expression of the aprotinin message in RNA (+)-strand tobacco mosaic virus vectors propagated in non-transgenic Nicotiana plants. This is a recombinant form of the native, bovine-sequence aprotinin, which is traditionally isolated from bovine lung by methods involving fractional precipitation, gel filtration, and ion exchange chromatography. Unlike animal-derived aprotinin, this product is isolated and purified from plant tissue by proprietary methods.
Other Notes
One trypsin inhibitor unit (TIU) will decrease the activity of 2 trypsin units by 50% where one trypsin unit will hydrolyze 1.0 μmole of N-α-benzoyl-DL-arginine p-nitroanilide (BAPNA) per min at pH 7.8 at 25 °C.

ReadyShield® phosphatase and protease inhibitor cocktail FAQ for sample protection in a variety of cell types and tissue extracts, including mammalian, plant, and microbial samples. Our ReadyShield® Protease Inhibitor Cocktail is a non-freezing solution that contains inhibitors with a broad specificity for serine, cysteine, acid proteases and aminopeptidases.
While aprotinin and bovine pancreatic trypsin inhibitor (BPTI) are the same protein sequence, the term aprotinin is typically used when describing the protein derived from bovine lung.

How does the storage temperature relate to shipping conditions?
1 answer-
The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment.

How should I store solutions of Product A6103, Aprotinin bovine?
1 answer-
We generally advise storing stock solutions of approximately 5-10 mg/mL. Working solutions down to 0.065 micrograms/mL can be stored refrigerated at 2-8°C for one week, or at - 20°C for appoximately six months in single use aliquots. See Table 2 in the Datasheet for details.
