CD40L/CD154/TRAP Protein, Rhesus Macaque (HEK293, Fc)

Cat. No.: HY-P75405
Handling Instructions

CD40L (CD154; TRAP) is a ligand to CD40/TNFRSF5, acts function by generating a costimulatory signal that up-regulates IL-4 synthesis. CD40L is specifically expressed on activated CD4+ T-lymphocytes and involves in activation of NF-κB/MAPK pathway. CD40L also involves in B cell differentiation, maturation, and apoptosis. CD40L in Rhesus Macaque, cleaved into a soluble form, acts as a ligand for integrins (ITGA5:ITGB1 and ITGAV:ITGB3). CD40L/CD154/TRAP Protein, Rhesus Macaque (HEK293, Fc) has a total length of 149 amino acids (M113-L261), is expressed in HEK392 cells with N-terminal hFc-tag.

Description

CD40L (CD154; TRAP) is a ligand to CD40/TNFRSF5, acts function by generating a costimulatory signal that up-regulates IL-4 synthesis[1]. CD40L is specifically expressed on activated CD4+ T-lymphocytes and involves in activation of NF-κB/MAPK pathway[2][3]. CD40L also involves in B cell differentiation, maturation, and apoptosis[4]. CD40L in Rhesus Macaque, cleaved into a soluble form, acts as a ligand for integrins (ITGA5:ITGB1 and ITGAV:ITGB3). CD40L/CD154/TRAP Protein, Rhesus Macaque (HEK293, Fc) has a total length of 149 amino acids (M113-L261), is expressed in HEK392 cells with N-terminal hFc-tag.

Background

CD40 Ligand (CD40L; CD154; TRAP) belongs to the tumor necrosis factor (TNF) family, is the ligand for CD40/TNFRSF5, specifically expressed on activated CD4+ T-lymphocytes[1].
CD40L is a type II transmembrane protein on B cells triggers important signals for B cell differentiation, maturation, and apoptosis[4].
CD40L acts function by cross-linking on T-cells to generate a costimulatory signal and thus enhances the production of IL4 and IL10 in conjunction with the TCR/CD3 ligation and CD28 costimulation, as well as promoting the production of interferon-γ, and TNF-α[1][4].
CD40L, binding with CD40 on antigen-presenting cells (APC), activates TNFR-associated factor 2- and IKK2-dependent pathways with stimulating I-κB kinase (IKK), increasing NF-κB DNA binding, and p65 nuclear translocation. The activation of I-κB kinase leads to strongly c-Jun N-terminal kinase activation as well as GST-I-κB and GST-p65 phosphorylation[2].
CD40L involves in MAPK pathways that strongly repress Bcl-6 with inducing the phosphorylation of Erk1/2, p38 and Jnk1/2 and activating IRF4 mediated by NF-κB[3].
CD40L also binds to and signals through several integrins, including αvβ3 and α5β1, which bind to the trimeric interface of CD40L. CD40L plays a major role in immune response and is a major target for inflammation[5].

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.

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 activity calculator equation

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

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