Stock solutions can also be prepared at 50-100 μg/mL in sterile buffer (PBS, HPBS, DPBS, or EBSS) containing carrier protein such as 0.2-1 % BSA or HSA and stored in working aliquots at -20 °C to -70 °C.

Buffer: 0.22 μm filtered protein solution is in 10 mM NaH2PO4, 150 mM NaCl, pH 7.2.

Handhabung: Avoid repeated freeze/thaw cycles.

Lagerung: -20 °C

Informationen zur Lagerung: Unopened vial can be stored between 2°C and 8°C for one month, at -20°C for six months, or at -70°C for one year.

Antigendetails

Target: IL1A (Interleukin 1 alpha (IL1A))

Andere Bezeichnung: IL-1alpha

Hintergrund: IL-1 was isolated from human blood that had been exposed to a pathogenic bacterium. IL-1 is a pyrogen, and it is an activating factor for lymphocytes. It also damaged joints and influenced liver proteins (2). IL-1α binds to the cell surface type I and II IL-1 receptors (IL-1RI and IL-1RII). IL-1 and -β and IL-1RA can compete for binding to these receptors. However, only IL-1RI, not IL-1RII, is functional because IL-1RII lacks a cytoplasmic domain and is thus unable to transmit signals to downstream steps (3). IL-1α is expressed by cancer cells and promotes angiogenesis and metastasis of pancreatic cancer and human gastric cancer cell lines (4). In addition, IL-1 induced the expression of VEGF in colon cancer (5).

Molekulargewicht: The 159 amino acid recombinant protein has a predicted molecular mass of 18,047 Da. The DTT-reduced and the non-reduced protein migrate at approximately 18kDa by SDS-PAGE. The N-terminal amino acid is Serine.
