CD40 Protein, Rat (HEK293, His)

CD40, also known as TNFR5, is a protein that exhibits defects in conserved residues necessary for feature annotation propagation. Specific residues missing in CD40 prevent the propagation of certain functional features associated with this protein. CD40 Protein, Rat (HEK293, His) is the recombinant rat-derived CD40 protein, expressed by HEK293 , with C-His labeled tag. The total length of CD40 Protein, Rat (HEK293, His) is 193 a.a., with molecular weight of ~28 kDa.

CD40, also referred to as TNFR5, is a protein that exhibits deficiency in conserved residue(s) essential for feature annotation propagation. The specific residue(s) missing in CD40 prevent the propagation of certain functional characteristics associated with this protein. CD40 is a member of the tumor necrosis factor receptor (TNFR) superfamily and plays a crucial role in immune regulation and activation of various immune cells.

Approximately 28 kDa

Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.

<1 EU/μg, determined by LAL method.

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

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.

Room temperature in continental US; may vary elsewhere.
