Usage
beta-HCG Protein-Centrifuge the standard vialat6000-10000 rpm for 30s.Reconstitute at 0.25mg/mL in 200 uL sterile water for short-term storage.

Reconstitution with 200 uL 50% glycerol solution is recommended for long term storage. Swirl or mix gently to insure complete and homogeneous solubilization.
Preparation and Storage
Store it under sterile conditions at -20°C upon receiving. Recommend to aliquot the protein into smaller quantities for optimal storage.**Avoid repeated freeze-thaw cycles.**

The recombinant protein is stable for up to 6 months from date of receipt at -80°C.
Other Notes
Small volumes of beta-HCG recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
Related Product Information for
beta-HCG recombinant protein
By restriction digest analysis, Talmadge et al. (1983) determined that the 7 CGB genes are extremely similar but not identical. Otani et al. (1988) found that CGB3 and CBG8 were expressed at 2-fold lower levels than CGB5 following transfection into a mouse adrenocortical cell line. Bo and Boime (1992) determined that most of the sequence variation among the CGB genes occurs in the nontranslated region of exon 1. They further found that CGB3 was expressedat about the same levels at CGB8 in first trimester placenta and in a choriocarcinoma cell line, and both were expressed at a lower level than CGB5. Jameson and Lindell (1988) determined that each of the CGB genes contains 3 exons. Otani et al. (1988) determined that the promoter regions contain no CAAT. or TATAA boxes.
