As you build cell-based assays and immunology workflows, you need consistent inputs—authenticated cell lines, cryopreserved PBMC, and sera you can trust. This Collection curates Thermo Fisher options and helps you compare formats, documentation, and lead times. Iright acts as your distributor partner, offering broad Thermo Fisher coverage and support on quotes, lot checks, and cold-chain logistics.
Choosing between cell lines, primary immune cells, and blood-derived products often depends on assay tolerance for variability, documentation requirements, and downstream readouts. The following scenarios map common research tasks to the right product types so you can move from options to orders faster.
When you narrow products, focus on attributes that directly affect your readouts. The quick guide below aligns selection with your assay constraints, documentation needs, and risk tolerance.
This short list highlights frequently selected items across FBS, human AB serum, PBMC, and representative cell lines. Use it to anchor lot reservations and documentation requests, then expand to adjacent SKUs as needed.

Serum choice shapes baseline signaling, complement activity, and batch-to-batch variability. Use this guidance to align product traits with your assay biology and compliance priorities.
In immunology or donor-like background needs, human AB serum avoids xenogeneic proteins and can reduce confounders in immune readouts. For general expansion, Gibco FBS remains a robust default with broad method compatibility and tight QC. Heat-inactivation (typically 56 °C, 30 min) is used where complement or certain serum factors interfere with readouts; skip it if your assay does not benefit, to preserve growth factors. For risk reduction or policy reasons, consider gamma-irradiated options; for clinical-adjacent research, evaluate xeno-free formulations.
Quick picking guide
Reducing variability begins with cell identity and cleanliness. Favor lines that ship with mycoplasma-free status, STR profiling, and recommended media/handling; then maintain consistent passage windows and thawing SOPs. RUO labeling applies to these products and calls for appropriate containment and training; ensure that CoA/SDS and any cell-specific user guides are available to your team and auditors. Thermo Fisher’s documentation around FreeStyle 293-F, for example, includes user guides and handling instructions.
Practical checks you can adopt
Cold-chain integrity matters as much as picking the right product. Coordinate dry-ice or liquid-nitrogen shipping windows, avoid weekend holds, and verify receiving freezers ahead of time. If your assay is lot-sensitive, work with Iright to reserve lots, request small verification samples where allowed, and align lead times with planned runs—especially for PBMC donors or premium-origin sera.
Typical logistics touchpoints
Clear answers reduce inbox back-and-forth and help new lab members make good choices. The short FAQ below covers what users ask most often when selecting and handling these materials.
1. Do I need heat-inactivated FBS for my assay?
If complement activity or select pathways (e.g., viral inactivation workflows, some immunology assays) interfere, heat-inactivation helps; otherwise, standard FBS maintains growth factor integrity and is generally preferred.
2. What PBMC viability should I expect after thaw?
Expect high viability when vials are thawed rapidly and diluted promptly into pre-warmed medium; follow vendor SOPs for recovery and rest steps, and confirm with trypan blue or flow viability dyes before stimulation.
3. Where do I find CoA, SDS, and handling instructions?
Most Thermo Fisher and Fisher Scientific product pages include downloadable CoA/SDS and, for cell lines, user guides. Store them with your internal lot records for audits and reproducibility.
4. How do I minimize variability across runs?
Reserve compatible lots for the duration of your study, lock thawing and passaging SOPs, and avoid mixing serum lots mid-series. Pair this with standard readouts (e.g., morphology, doubling time, marker expression) to detect drift early.
When you’re ready to proceed, Iright can assemble quotes, share CoA/SDS for target lots, and coordinate lot reservations and cold-chain schedules. Tell us your assay type, preferred origin/treatments (e.g., Gibco FBS HI, human AB serum), donor parameters for PBMC, and your target start date, and we’ll align product availability to your run plan. For cell lines, we can also add recommended media and supplements into the same cart for a clean kickoff.
