User Data, Western Blot KO, Customer Submission

Contribution from Undisclosed customer — April 26, 2018

Western blot using Anti-CD276 (B7-H3) antibody (HPA017139) in U2OS human bone osteosarcoma parental cell line and B7-H3 knockout (KO) U2OS cell line.


Western blot shows lysates of U2OS human bone osteosarcoma parental cell line and B7-H3 knockout (KO) U2OS cell line.

PVDF membrane was probed with 0.5 ug/mL of Anti-CD276 (B7-H3) antibody (HPA017139). A specific band was detected for B7-H3 at approximately 95 kDa (as indicated) in the parental U2OS cell line, whereas in the knockout U2OS cell line no band was detected

The experiment was conducted under reducing conditions.
