Quantitative Immunological Assays to Assess HIV Antibodies and Vaccines

我们是一个核心实验室，为疫苗研究中心内的实验室、其他内部实验室以及世界各地的合作者提供艾滋病毒抗体检测服务。我们的大部分工作都使用了标准化的HIV-1中和试验。我们对接种疫苗的动物和HIV感染者的血清样本、从这些受试者分离的抗体以及为提高广度、效力和可制造性而设计的变异抗体进行这种检测。我们还开发和维护这些检测所需的试剂，包括天然和突变病毒基因、病毒库存和参考抗体库存。我们最近通过将机器人液体处理集成到我们的方案中，增加了我们的检测的吞吐量。此外，我们还提供分析和图表来解释我们的数据，以及来自VRC VIP实验室的相关数据；这些数据正被VRC和合作者用于选择候选临床产品。我们还向一家制药公司的合作者提供数据，为他们开发临床试验产品的决定提供信息。

We are a Core lab providing HIV antibody assay services to labs within the Vaccine Research Center, other intramural labs, and for collaborators around the world. Most of our work uses a standardized HIV-1 neutralization assay. We perform this assay on serum samples from vaccinated animals and HIV-infected individuals, on antibodies isolated from such subjects, and on variant antibodies engineered for improved breadth, potency, and manufacturability. We also develop and maintain the reagents needed for these assays, including natural and mutant virus genes, stocks of viruses, and stocks of reference antibodies. We recently have increased the throughput of our assay by integrating robotic liquid handling into our protocols. In addition, we provide analysis and graphics to allow interpretation of our data, as well as related data from the VRC VIP lab; these are being used for selection of candidate clinical products at the VRC and by collaborators. We also provide data to collaborators at a pharma company to inform their decisions on developing products for clinical trials.
