Val 35-Asn 242

Endotoxin

Less than 1.0 EU per ug by the LAL method.

Purity

>95% as determined by SDS-PAGE.

Storage

For long term storage, the product should be stored at lyophilized state at -20°C or lower. Please avoid repeated freeze-thaw cycles. This product is stable after storage at: -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution.

Reconstitution

It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 mg/ml. Centrifuge the vial at 4ºC before opening to recover the entire contents.

SDS-PAGE

Cynomolgus / Rhesus macaque B7-1, His Tag (HPLC-verified) on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

HPLC

The purity of Cynomolgus / Rhesus macaque B7-1, His Tag (HPLC-verified) was more than 90% as determined by SEC-HPLC.
