LIFR Protein, Human (HEK293, hFc-Flag)

Cat. No.: HY-P700418
Handling Instructions

LIFR Protein, a signal-transducing molecule, potentially shares a common pathway with IL6ST. Its soluble form inhibits LIF binding to target cell receptors, reducing biological activity. LIFR forms a heterodimer with IL6ST, interacting with the CNTF and CNTFR complex, implying potential crosstalk and collaborative actions in cellular processes. LIFR Protein, Human (HEK293, hFc-Flag) is the recombinant human-derived LIFR protein, expressed by HEK293 , with C-hFc, C-Flag labeled tag. The total length of LIFR Protein, Human (HEK293, hFc-Flag) is 789 a.a., with molecular weight of 119.3 kDa.

Background

LIFR protein acts as a signal-transducing molecule that may share a common pathway with IL6ST. Its soluble form functions as an inhibitor by blocking the binding of LIF to receptors on target cells, thereby suppressing its biological activity. LIFR forms a heterodimer with IL6ST, and this heterodimer interacts with the complex formed by CNTF and CNTFR, suggesting potential crosstalk and collaborative actions in cellular processes.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Reconstitution Calculator

  • Dilution Calculator

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×
C1   V1   C2   V2

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
