Hamny Hamny

thank you Mr. Mohammed for your help

the negative control is not stained but the cells that immunoreactive to FSH Ab were found in pars nervosa of pituitary gland not in pars distalis of the gland. Is it rigth if we refer to the theory?

Sri Wahyuni

FSH cells only found in pars distalis of pituitary gland among other endocrine cells. The sturcture between pars distalis and pars nervosa of that glands is quite different. Therefore, there are no positive reaction of ir-FSH cells found in pars nervosa.

thank you Mrs Sri

maybe there is something with our IHC protocol.
