Recombinant Human CD30/TNFRSF8

Description :

Recombinant Human CD30 is produced by our Mammalian expression system and the target gene encoding Phe19-Lys379 is expressed with a 6His tag at the C-terminus.

Formulation :

Lyophilized from a 0.2 米m filtered solution of 20mM Tris,150mM NaCl,pH 7.5.

Purity :

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

Endotoxin :

Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.

Reconstitution :

Dissolve the lyophilized protein in distilled water.

Storage :

Lyophilized protein should be stored at < -20～C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7～C for 2-7 days.Aliquots of reconstituted samples are stable at < -20～C for 3 months.

Background :

CD30, also known as TNFRSF8, is a cell membrane protein of the tumor necrosis factor receptor family, which regulates proliferation/apoptosis and antibody responses. CD30 is expressed by activated, but not by resting, T and B cells. Aberrant expression of CD30 by mastocytosis mast cells and interaction with its ligand CD30L (CD153) appears to play an important role in the pathogenesis and clinical presentation of systemic mastocytosis. CD30 has been considered as a specific diagnostic biomarker of anaplastic large cell lymphoma (ALCL) and classical Hodgkin lymphoma (cHL). CD30 is also a biomarker used for targeted therapy by an antibody每drug conjugate.
