Cat. No.: HY-P70681
Handling Instructions

4-1BBR/TNFRSF9 Protein, Human (HEK 293, Fc), a recombinant human 4-1BBR/TNFRSF9 Protein produced in HEK293 cells, has an Fc fragment at the C-terminus. Recombinant Human 4-1BBRTNFRSF9, an inducible T cell molecule belonging to the TNF receptor superfamily, could promote the expansion of antigen-specific T cells and prevent activation-induced death of CD8+ T cells.

Description

4-1BBR/TNFRSF9 Protein, Human (HEK 293, Fc), a recombinant human 4-1BBR/TNFRSF9 Protein produced in HEK293 cells, has an Fc fragment at the C-terminus. Recombinant Human 4-1BBRTNFRSF9, an inducible T cell molecule belonging to the TNF receptor superfamily, could promote the expansion of antigen-specific T cells and prevent activation-induced death of CD8+ T cells[1].

Background

Recombinant Human 4-1BBRTNFRSF9 (CD137) is an inducible T cell molecule belonging to the TNF receptor superfamily. It has been shown that signaling through CD137 by either its natural ligand, 4-1BBL, or by agonistic Ab’s costimulates activation of CD4+ and CD8+ T cells in a CD28-independent fashion, leading to activation of the NF-κB, c-Jun NH2-terminal kinase/stress-activated protein kinase (JNK/SAPK), and p38 signaling pathways. In addition to its role in promoting the expansion of antigen-specific T cells, CD137 signaling may also prevent activation-induced death of CD8+ T cells[1].

Biological Activity
0.03 μg/mL (100 μL/well) of immobilized Human 4-1BBL-His can bind Human 4-1BB-Fc with an ED50 value of 6.86 μg/mL.

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)
× = ×

The specific active calculator equation

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

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