Technical Data
SARS, Spike Protein (Severe Acute Respiratory Syndrome, SARS-CoV, SARS Associated Coronavirus)
A novel coronavirus has recently been identified as the causative agent of SARS (Severe Acute Respiratory Syndrome) (1-2). Coronaviruses are a major cause of upper respiratory diseases in humans (3). The genomes of these viruses are positive-stranded RNA approximately 27-31kb in length. SARS infection can be mediated by the binding of the viral spike protein, a glycosylated 139kD protein and the major surface antigen of the virus, to the angiotensin-converting enzyme 2 (ACE2) on target cells. This binding can be blocked by a soluble form of ACE2 (4).

Suitable for use in ELISA. Other applications not tested.

Recommended Dilution:
ELISA: Detects 10ng of free peptide at 1ug/ml.
Optimal dilution determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), aliquot and store at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
