Recombinant Mouse IL-3 Rβ

Measured by its ability to inhibit the IL-3-induced proliferation of NFS‑60 mouse myelogenous leukemia lymphoblast cells. The ED₅₀ for this effect is 0.2‑1 µg/mL in the presence of 2.5 µg/mL soluble rmIL-3 R alpha /Fc and 0.5 ng/mL of rmIL-3.

Lyophilized

The predicted molecular weight of Recombinant Mouse IL-3 Rβ is Mr 74.9 kDa. However, the actual molecular weight as observed by migration on SDS-PAGE is Mr 80 kDa.

74.9

This recombinant protein was 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 with no calcium, magnesium, or preservatives.

This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. See Product Insert for exact lot specific storage instructions.
