Recombinant Human Insulin-Like Growth Factor-Binding Protein 4/IGFBP-4 is produced by our mammalian expression system in human cells. The target protein is expressed with sequence (D22-E258) of Human IGFBP4 fused with a polyhistidine tag at the C-terminus.

Format
Lyophilized
Rekonstitution
It is not recommended to reconstitute to a concentration less than 100 μg/mL. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
Buffer
Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.2.
Handhabung
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
Lagerung
4 °C/-20 °C/-80 °C
Informationen zur Lagerung
Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
Haltbarkeit
3 months

IGFBP4
(Insulin-Like Growth Factor Binding Protein 4 (IGFBP4))
IGFBP-4, whose full name is insulin-like growth factor-binding protein 4, is induced by forskolin and N6, O2’dibutyryl sdenosine 3’, or 5’-cyclic monophosphate. It contains IGFBP N-terminal domain and thyroglobulin type-1 domain, and can bind IGF2. The IGF-binding proteins can prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. Alternative Names: Insulin-Like Growth Factor-Binding Protein 4, IBP-4, IGF-Binding Protein 4, IGFBP-4, IGFBP4, IBP4
