Product

Sample compliance: samples are collected at the hospital site under a collaborative project development model, with all procedures conducted under regulatory oversight.

Sample diversity: rich ethnic diversity (Asian/Black/Caucasian) with ample inventory (several hundred donors of different nationalities).

Standardized processes: managed under near-GMP procedures with strict operational process control.

Extensive experience: the collection team has experience supporting IIT sample collection and project submissions, ensuring sample safety and traceability while providing authentic and accurate data.

Process optimization: a dedicated R&D team, including QC and QA, provides strong support for the development and refinement of the entire process workflow.

Service Item | Service Specification:

• Irradiated PBMC preparation service (single donor source): 50 / 10 / 5 million

• Irradiated PBMC preparation service (pooled source, 5 donors): 50 / 10 / 5 million

Delivery specifications:

• Cell count: exceeds the delivery specification

• Cell viability: ≥ 80%

• Mycoplasma testing: < 5 EU/mL (research grade)

• Bacterial, yeast, and fungal testing: negative

• Disintegration test: after 14 days of post-thaw culture, the residual cell rate is < 10%

Disintegration assay of irradiated PBMCs: Samples 1 and Sample 2 were irradiated with X-rays at 30 Gy and 40 Gy, respectively, and were essentially completely disintegrated after 13 days of culture.
