摘要

C3H/HeJ小鼠在皮下注射可移植乳腺腺癌(H2712)后不同时间的特异性肿瘤相关免疫反应,采用毛细管放射性(111In)白细胞粘附抑制(LAI)测定。采用特异性肿瘤和其他不同组织学来源的可移植肿瘤经一期1-丁醇萃取制备的可溶性肿瘤相关抗原评价LAI的反应性。该试验被发现能够在触诊检测到皮下肿瘤之前检测到显著的抗肿瘤反应。在肿瘤直径大于20mm之前,这种反应一直很明显。

A radio (111In) capillary tube leukocyte adherence inhibition assay for the detection of specific tumor-associated immunity.

The specific tumor-associated immune response of C3H/HeJ mice was determined at various times after subcutaneous injection with a transplantable mammary adenocarcinoma (H2712) using a radio (111In) leukocyte adherence inhibition (LAI) assay carried out in capillary tubes. Solubilized tumor-associated antigen prepared by a single phase 1-butanol extraction of the specific tumor and other transplantable tumors of different histological origin were used in the evaluation of LAI reactivity. The assay was found to be capable of detecting a significant antitumor response before the subcutaneous tumors became detectable by palpation. The response remained significant until the tumors were greater than 20 mm in diameter.
