Pro-Caspase-3/Pro-CASP3 Protein, Human (277a.a, His)

Pro-Caspase-3/Pro-CASP3 Protein, Human (277a.a, His) is the recombinant human-derived Caspase-3/CASP3, expressed by E. coli , with N-His labeled tag.

Measured by its ability to cleave 50 µM fluorogenic peptide substrate Ac-DEVD-AFC(HY-P1005) that incubate at room temperature in kinetic mode for 5 minutes. The specific activity is >500 pmol/min/μg. (The proenzyme needs to be activated by Caspase-8 for an activated form.)

Full Length

Approximately 34 kDa

• 
  Greater than 90% as determined by reducing SDS-PAGE.

Lyophilized powder

Lyophilized from a 0.22 μm filtered solution of 20 mM Tris-HCL, 150 mM NaCl, pH 8.0, 5 mM DTT, 0.2% SKL.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 50 µg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. 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.
