PRODUCT

Recombinant Human IL1B / IL-1beta was expressed from E.coli. Its molecular weight is 17.5KD. Protein sequence: Ala117-Ser269 of Uniprot accession number P01584.
gene name IL1B
alias IL1B, Interleukin 1 beta, IL-1, IL1-BETA, IL1F2
host species Human
production host E.coli
tags None
purity Greater than 95% as determined by reducing SDS-PAGE.
endotoxin Less than 0.1 ng/ug (1 IEU/ug) as determined by LAL test.
formulation Protein in [20mM PB,150mM NaCl,pH7.4] was 0.22 um filtered before lyophilized. Usually protectant (mannitol or trehalose) was added before lyophilization.
reconstitution Reconstitute lyophilized powder with water to no less than 100 ug/ml, solubilize at RT for 30 min with occasional gentle mixing. It is recommended that 0.1% HSA (SDP1139) be added as a carrier protein for long term storage.
shipping Ship at ambient conditions
storage Lyophilized form is stable at room temperature for 3 weeks. Keep at -20°C for long term storage. After reconstitution, store at 4°C for 2-7 days or at below -20°C for up to 3 months.
