Description
Recombinant Human Cytotoxic T-lymphocyte protein 4 is produced by our Mammalian expression system and the target gene encoding Lys36-Asp161 is expressed with a 6His tag at the C-terminus.
Alias
Cytotoxic T-lymphocyte protein 4; Cytotoxic T-lymphocyte-associated antigen 4; CTLA-4; CD152; CTLA4
Endotoxin Testing
Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.
Purity
Greater than 95% as determined by reducing SDS-PAGE.
Activity
Measured by its ability to bind Mouse B7-1 in functional ELISA.The ED50 for this effect is less than 20 ng/ml.
Formulation
Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.
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.
Warranty
For Research Use Only. Our recombinant proteins can not be used in diagnostic procedures.
