Cat. No.: HY-P78091
COA Handling Instructions

CD40 protein is a TNFSF5/CD40LG receptor that transduces signals through TRAF6 and MAP3K8-mediated pathways, activates ERK in macrophages and B cells, and induces immunoglobulin secretion. CD40 exists as monomers and homodimers and interacts with TRAF proteins (TRAF1, TRAF2, TRAF3, TRAF5, and TRAF6). CD40 Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived CD40 protein, expressed by HEK293 , with C-Avi, C-His labeled tag. The total length of CD40 Protein, Human (Biotinylated, HEK293, His-Avi) is 173 a.a., with molecular weight of 35-40 kDa.

Description

CD40 protein is a TNFSF5/CD40LG receptor that transduces signals through TRAF6 and MAP3K8-mediated pathways, activates ERK in macrophages and B cells, and induces immunoglobulin secretion. CD40 exists as monomers and homodimers and interacts with TRAF proteins (TRAF1, TRAF2, TRAF3, TRAF5, and TRAF6). CD40 Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived CD40 protein, expressed by HEK293 , with C-Avi, C-His labeled tag. The total length of CD40 Protein, Human (Biotinylated, HEK293, His-Avi) is 173 a.a., with molecular weight of 35-40 kDa.

Background

CD40 Protein, acting as the receptor for TNFSF5/CD40LG, is instrumental in transducing signals through TRAF6- and MAP3K8-mediated pathways, leading to the activation of ERK in macrophages and B cells and subsequent induction of immunoglobulin secretion. Existing in both monomeric and homodimeric forms, CD40 Protein exhibits variations in its homodimeric structure, as observed in the bladder carcinoma cell line Hu549. The receptor interacts with key signaling molecules such as TRAF1, TRAF2, TRAF3, TRAF5, and TRAF6, with the crucial interaction occurring between CD40 Protein, TRAF6, and MAP3K8, thereby playing a pivotal role in ERK activation.

Biological Activity

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O.

Storage & Stability

Stored at -20°C for 2 years. 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.

Shipping

Room temperature in continental US; may vary elsewhere.

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
