In Vitro
In Vitro	The cell binding ratio of ¹²⁵I-Nivolumab and ¹²⁵I-Nivolumab-DTPA to PD-1 is 13.78 ± 2.90% and 10.22 ± 2.62%, respectively. Conjugating of DTPA does not affect targeting of Nivolumab to PD-1 in vitro.^[1]
細胞実験	Splenocytes were isolated from the spleens obtained from humanized PD-1 over-expressing mice following standard protocol. ¹²⁵I labeled Nivolumab and Nivolumab-DTPA, respectively. To perform co-culture, ¹²⁵I-Nivolumab and ¹²⁵I-Nivolumab-DTPA (0.37 MBq/µg) were added to the freshly isolated splenocytes (1×10⁶ cells) grown in 6-well plates, respectively. After incubation for 12 h at 4°C, cells were collected after rinsing three times with PBS. ¹²⁵I radioactivity was determined in a gamma counter to evaluate their binding efficiency to PD-1.

In Vivo
In Vivo	In SPECT images, lesions with high ^99mTc-DTPA-nivolumab uptake and relatively clear background are shown at 6 h. Thereafter, the suspected intestinal thickening in Gd-free T1WI is observed at 2 h after the addition of Gd-DTPA-nivolumab.^[1]

よくある質問（FAQ）

質問：1：
How to store the antibody?

回答：
Store the undiluted solution at 4 °C in the dark. Freezing antibodies can result in a loss of activity caused by the freezing/thawing process. Diluting antibodies to working concentrations and storing at 4°C for more than a day should be avoided. Additionally, make sure to keep the antibody sterile. Under these storage conditions, your antibodies should remain active for up to one year and oftentimes longer.
