Frozen section immunohistochemistry for fixation sensitive nuclear antigens, such as MYC and BRCA1
Cryostat Frozen Sectioning Aid(CFSA) which permits the rapid and facile preparation of high quality, freeze substituted frozen sections is being adapted to the application of avidin-peroxidase conjugates and cytochemical peroxidase staining procedures. We have developed improved immunohistological techniques for detecting extremely fixation sensitive nuclear antigens in frozen tissue sections of the human breast and colon. We have localized BRCA1 protein in epithelial cell nuclei of human sporadic cancer and co-localized two BRCA1 antibodies with antibodies to nucleolin. Both the nuclear and nucleolar localization of BRCA1 is under further investigation.

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.
Dr.Tulchin is not currently required to report Industry relationships.
Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website. Patients may wish to ask their physician about the activities they perform for companies.
Mount Sinai Health System (MSHS) physicians - including those employed by MSHS - do not always participate in the same health plans in which MSHS hospitals or facilities participate.
Information regarding insurance participation and billing by this physician may be found on this page or obtained by contacting this provider directly.
Insurance plans that the Mount Sinai Health System hospitals or facilities participate in can be found on the Mount Sinai Health System website.
