Size

£219.00

SKU:: PME100838
Additional Names:: IL-1;IL1-BETA;IL1beta;IL1F2
Molecular Weight:: The protein has a predicted molecular mass of 43.5 kDa after removal of the signal peptide.The apparent molecular mass of IL1B-hFc is approximately 35-55 kDa due to glycosylation.
Purity:: The purity of the protein is greater than 95% as determined by SDS-PAGE and Coomassie blue staining.
Storage Conditions:: Store at -20[o]C to -80[o]C for 12 months in lyophilized form. After reconstitution; if not intended for use within a month; aliquot and store at -80[o]C (Avoid repeated freezing and thawing). Lyophilized proteins are shipped at ambient temperature.
Supplier:: DIMA Biotechnology Ltd
Formulation:: Lyophilized from sterile PBS; pH 7.4. Normally 5 % - 8% trehalose is added as protectants before lyophilization. Please see Certificate of Analysis for specific instructions of reconstitution.
Target:: IL1B
IL1B(Ala117-Ser269) hFc(Glu99-Ala330):: IL1B(Ala117-Ser269) hFc(Glu99-Ala330)
Extra Details:: The protein encoded by this gene is a member of the interleukin 1 cytokine family. This cytokine is produced by activated macrophages as a proprotein; which is proteolytically processed to its active form by caspase 1 (CASP1/ICE). This cytokine is an important mediator of the inflammatory response; and is involved in a variety of cellular activities; including cell proliferation; differentiation; and apoptosis. The induction of cyclooxygenase-2 (PTGS2/COX2) by this cytokine in the central nervous system (CNS) is found to contribute to inflammatory pain hypersensitivity. Similarly; IL-1B has been implicated in human osteoarthritis pathogenesis. Patients with severe Coronavirus Disease 2019 (COVID-19) present elevated levels of pro-inflammatory cytokines such as IL-1B in bronchial alveolar lavage fluid samples. The lung damage induced by the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is to a large extent; a result of the inflammatory response promoted by cytokines such as IL-1B. This gene and eight other interleukin 1 family genes form a cytokine gene cluster on chromosome 2. [provided by RefSeq; Jul 2020]
