Immunological reagents could be a useful adjunct. Human monoclonal antibodies derived from patients with astrocytic tumors might recognize subtle antigenic specificities that would differ from those recognized by xenogeneic (murine) systems. Five hybridomas, designated as BT27\/1A2, BT27\/2A3, BT32\/A6, BT34\/A5, and BT54\/B8, were produced from the fusion of peripheral blood lymphocytes of four patients with astrocytic tumors to the human myeloma-like cell line TM-H2-SP2. This cell line has a 46, XX karotype and is negative for hypoxanthine guanine phosphoribosyltransferase. All five human monoclonal antibodies produced 2.4 to 44 \u00b5g\/ml of immunoglobulin M, had a similar but not identical pattern of reactivity against a panel of human tumor cell lines, and failed to react with normal human astrocytes. Labeling of four neuroectodermal tumor explant cultures by BT27\/2A3 was demonstrated by flow cytometry. Karyotyping of three of the five hybridomas demonstrated that two were pseudodiploid (2\u20133n) and one hypodiploid (&lt; 2n). The monoclonality of the hybridomas was evaluated by Southern blot analysis of J<jats:sub>H<\/jats:sub> gene rearrangements, revealing two types of rearrangements for each hybridoma, both consistent with monoclonality. Preliminary antigen characterization indicated that at least four of the five human monoclonal antibodies were directed to cell-surface glycolipids.<\/jats:p>","DOI":"10.3171\/jns.1992.76.4.0660","type":"journal-article","created":{"date-parts":[[2009,5,26]],"date-time":"2009-05-26T20:58:41Z","timestamp":1243371521000},"page":"660-669","source":"Crossref","is-referenced-by-count":10,"title":["Human antiglioma monoclonal antibodies from patients with astrocytic tumors"],"prefix":"10.3171","volume":"76","author":[{"given":"Michael D.","family":"Dan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christopher M.","family":"Schlachta","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Guy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard G.","family":"McKenzie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Delbert R.","family":"Dorscheid","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Victor A.","family":"Sandor","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean-Guy","family":"Villemure","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gerald B.","family":"Price","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"175","DOI":"10.3171\/jns.1989.70.2.0175","article-title":"Intratumoral LAK cell and interleukin-2 therapy of human gliomas.","volume":"70","author":"Barba","year":"1989"},{"key":"b2","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"589","DOI":"10.3171\/jns.1988.68.4.0589","article-title":"Imbalances in T cell subpopulations in human gliomas.","volume":"68","author":"Bhondeley","year":"1988"},{"key":"b3","series-title":"Scand J Clin Lab Invest","first-page":"77","article-title":"Isolation of mononuclear cells and granulocytes from human blood.
