LIFR Protein, Mouse (HEK293, His)

LIFR Protein, a signal-transducing molecule, may share a common pathway with IL6ST. Its soluble form acts as an inhibitor, blocking LIF binding to receptors and reducing biological activity. LIFR forms a heterodimer with IL6ST, interacting with the CNTF and CNTFR complex, indicating potential cross-talk and cooperative actions in cellular processes. LIFR Protein, Mouse (HEK293, His) is the recombinant mouse-derived LIFR protein, expressed by HEK293 , with C-His labeled tag.

LIFR protein is a signal-transducing molecule that potentially shares a common pathway with IL6ST. Its soluble form acts as an inhibitor, blocking the binding of LIF to receptors on target cells, thus dampening its biological activity. LIFR forms a heterodimer with IL6ST, and this complex interacts with the complex formed by CNTF and CNTFR, suggesting potential cross-talk and cooperative actions in cellular processes.

Measured by its ability to inhibit LIF-dependent proliferation of TF-1 human erythroleukemic cells. The ED₅₀ for this effect is 1.051 μg/mL, corresponding to a specific activity is 9.51×10^2 units/mg.

  ≥ 95%, as determined by reducing SDS-PAGE.

Lyophilized powder

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
