样本收集|Overview

血液

在薰衣草顶(EDTA钾)管中收集了用于DNA研究的血液,然后在室温下储存并运往我们。

血液for serum or plasma studies needs to be processed locally on the same day the blood is collected, then stored and shipped to us frozen.

  • For adults, it is generally safe to collect 20 ml of blood.
  • 对于2岁以上的儿童,通常可以安全地收集10毫升的血液。但是,这取决于孩子的医学状况以及是否还需要收集其他用于非研究目的的血液样本。
  • 对于2岁以上的儿童,通常可以安全地收集3毫升的血液。但是,这取决于孩子的医学状况以及是否还需要收集其他用于非研究目的的血液样本。

滑液

我们被允许接收在医学指示的诊断或治疗过程中收集的滑液,否则将被丢弃。目前,我们没有同意书,使我们能够接收仅出于研究目的而收集的滑液。

最佳地,我们希望按下所述的过程在本地处理滑液。但是,如果无法在本地处理样品,则可以在室温下直接将滑液运送到我们。滑液的局部处理程序:

  1. Expel synovial fluid (SF) from the syringe (without needle) into a polypropylene tube and immediately place on ice.
  2. 在4°C下以1000 x g离心5分钟。
  3. 上清液应转移到新的管中,并按照步骤4进行处理。沉淀物通常含有滑膜细胞,并在5-10 mL的细胞培养基上含有含有抗生素的细胞培养基,例如许多医院实验室使用的培养基收集的培养基皮肤活检样品。如果提前几天与您联系,我们可以为您提供细胞培养基。由于美国海关服务和农业部限制了包含非人类产品的细胞的进口,例如(胎牛血清,FBS),不使用含FBS的培养基。培养基中的细胞可以在室温下运输。
  4. The supernatant from step 3 should be centrifuged again for 1 hour at 20,000 x g at 4°C, separated from the precipitate, and frozen at 20°C. The frozen synovial fluid can be shipped on dry ice.

软骨,滑膜,皮肤和骨头

We are permitted to receive tissue samples that are collected during a medically-indicated diagnostic or therapeutic procedure and would otherwise have been discarded. At this time, we do not have a consent form that allows us to receive tissue samples that are collected solely for research purposes.

组织样品可用于恢复活细胞和/或研究疾病如何影响完整组织的结构或功能。因此,我们可能会要求将组织样品分成不同的容器并进行处理,以便我们可以通过几种方式进行研究。请contact usbefore any procedure in which you think tissue samples will be available for research.

Tissue samples used to recover living cells should be covered with 3 volumes of cell culture medium containing antibiotics, such as the medium used by many hospital labs for collecting skin biopsy samples. We can provide you with cell culture medium if we are contacted several days in advance. Since the United States Customs Service and Department of Agriculture restrict the importation of samples that contain non-human products, such as (fetal bovine serum, FBS), do not use FBS-containing culture medium. The tissue in culture medium can be shipped at room temperature. Ship immediately even if this means a sample may arrive on the weekend, but let us know ahead of time so that we can make arrangements for special weekend receipt.

组织样品可能需要不同类型的处理,具体取决于正在进行的分析类型。可能需要将样品闪烁在液氮中,存储-80°C,并在干冰上运送到我们身上,或者可能需要将其放入标准固定剂(缓冲福尔马林)或电子显微镜固定剂中。如果提前几天与我们联系,我们可以为您提供适当的固定剂。

由于某些组织样品可以用于几个不同的研究目的,因此最好在任何计划可用于研究的计划程序之前与我们联系。

Cheek swabs

在必要时,我们可以从参与者那里收集脸颊拭子或唾液样本,以恢复DNA进行医学研究。如果您认为不可能提供血液样本,请contact us, and we can arrange to have a cheek swab or saliva collecting kit sent to you.

所有文件和样本应通过隔夜交货发送。通过提前与我们联系,我们可以提供联邦快递或DHL运输帐号,以便将运输费直接向中心收取遗传骨骼疾病中心。
