Objective:
To prepare and identify human monoclonal antibody against IL-1 receptor accessory protein (IL1RAP), which is a new identified surface marker for leukemia stem cells (LSC).
Methods:
BALB/c mice were inoculated intraperitoneally with hybridoma cells (3H6E10, 10D8A7) and their ascites were collected. The monoclonal antibody against hu-IL1RAP specifically was purified from ascites, the nondenaturing-PAGE, ELISA and Western blot were used to detect the purity, titer and sensitivity of antibody.
Results:
Two purified antibodies were obtained and named as 3H6E10 McAb and 10D8A7 McAb, whose purity was 95% and 94% respectively. The titer of two purified monoclonal antibodies was 1 : 81000 and specific conjugation of IL1RAP purified protein and endogenous protein from normal people and leukemia patients with purified antibodies were confirmed.
Conclusion:
The purified monoclonal antibodies which can specifically bind to hu-IL1RAP are successfully prepared, thus providing novel way to effectively clear LSC in the future.
