Recombinant TOXGO ROP4 encodes the immunodominant sequences of the Toxoplasma Dense Granule protein. Recombinant ROP4 contains an N terminal GST purification tag and migrates as an approximately 43 kDa protein under non-reducing conditions and reducing conditions in SDS-PAGE.
Purity
>95%, as determined by SDS-PAGE.
Applications
Toxoplasma ROP4 antigen is suitable for ELISA and Western blots, excellent antigen for detection of Toxoplasma with minimal specificity problems.
Presentation
Lyophilized from 50mM Tris-HCl, 60mM NaCl and 50% glycerol.
Reconstitution
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Storage
The lyophilized protein is stable for at least 2 years from date of receipt at -20° C. Upon reconstitution, this protein can be stored in working aliquots at 2° - 8° C for one month, or at -20° C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
