随着免疫学上应用放射性同位素科研工作的深入开展,人们迫切地要求从手工制备同位素样品中摆脱出来。国外Hartzman等、Lefkovits和Kamber、Sanderson等、Harrison等分别设计了原理相似的多头样品收集器(简称MASH),用来收集用微量板培养同位素掺入的淋巴细胞。主要用于测量混合淋巴细胞反应、抗原或有丝分裂因子刺激引起的淋巴细胞增殖反应、抑制细胞、抑制因子、促分裂素和细胞介导的细胞毒反应等研究方面。目前国外许多免疫实验室已把MASH作为不可缺少的仪器。 我们自行设计和制造了适用于一次能收集10个样品的10×75毫米试管培养的淋巴细胞的收集器。经过两年来多次改进定名为S-80型半微量多头样品收集器(简称S-80型收集器),它具有结构简单、操作方便、性能良 With the advent of immunological applications of radioisotope research, there is an urgent need to get rid of hand-made isotope samples. Foreign Hartzman et al., Lefkovits and Kamber, Sanderson et al., Harrison et al. Designed a multi-head sample collector (MASH) similar in principle to collect isotope-spiked lymphocytes with microplates. Mainly used to measure mixed lymphocyte reaction, antigen or mitogen-induced lymphocyte proliferation response, inhibition of cells, inhibitory factors, mitogen and cell-mediated cytotoxic reactions and other research. At present, many foreign immunization laboratories have MASH as an indispensable instrument. We designed and built our own collection of 10 × 75 mm tube cultures of lymphocytes capable of collecting 10 samples at a time. After several years of improvement, it has been named the S-80 semi-micro multi-head sample collector (S-80 collector for short) and has the advantages of simple structure, convenient operation, good performance
