标签：冷冻人白细胞(5.0 Billion Cells)

Cryopreserved human leukapheresis product collected from normal peripheral blood, containing ≥5.0 billion cells.

从正常外周血中采集的冷冻保存的人白细胞分离产品，含有≥50亿个细胞。

Product Overview

A leukopak is a highly-enriched leukapheresis-derived product obtained from an IRB-approved collection facility. Leukopaks contain higher concentrations of mononuclear cells, B cells, T cells, stem/progenitor cells, dendritic cells, and other cell types as compared to standard venipuncture collection methods or buffy coat products.

The total volume and concentration of the supplied cells will vary. Based on this count, the product is filled to deliver not less than 5.0 billion cells upon thaw.

Leukopaks typically contain up to 50% T cells, 20% monocytes, 10% B cells, and 10% NK cells, 3% granulocytes, and 3 % hematocrit. Actual percentages will vary from donor to donor.

Cyropreserved leukopaks are frozen quickly after collection using a controlled rate method to maximize viability.

Additional shipping charges apply for cryopreserved leukopaks.

leukopak 是从 IRB 批准的收集设施中获得的高度富集的白细胞分离衍生产品。 与标准静脉穿刺采集方法或血沉棕黄层产品相比，Leukopaks 含有更高浓度的单核细胞、B 细胞、T 细胞、干细胞/祖细胞、树突细胞和其他细胞类型。

提供的细胞的总体积和浓度会有所不同。 基于此计数，该产品在解冻后被填充以提供不少于 50 亿个细胞。

Leukopaks 通常含有高达 50% 的 T 细胞、20% 的单核细胞、10% 的 B 细胞和 10% 的 NK 细胞、3% 的粒细胞和 3% 的血细胞比容。 实际百分比会因捐赠者而异。

冷冻保存的白细胞在收集后使用受控速率方法快速冷冻，以最大限度地提高生存能力。

冷冻保存的白细胞需支付额外的运费。
