Physical State:

Lyophilized

Formulation:

Lyophilized from a sterile filtered (through a 0.2 �m filter) solution in PBS, pH 7.4.

Purity:

>97% by SDS-PAGE and HPLC analyses.

Biological Activity:

Fully biologically active when compared to standard.

Reconstitution:

Centrifuge vial prior to opening. Reconstitute in sterile ddH2O to a concentration of 0.1-1.0 mg/ml. The solution can then be further diluted in other aqueous buffers.

Storage/Stability:

Lyophilized protein is stable at 2-4℃C, but is preferably stored desiccated at -20℃C. After reconstitution, stable for ?1 week at 2-4℃C. For long term storage, aliquot and store at -20℃C to -80℃C. Avoid repeated freeze-thaw c
