<h2 data-section-id="f727ot" data-start="0" data-end="41">What are interferons and interleukins?</h2>
&nbsp;
Interferons (IFN-alpha, IFN-beta, IFN-gamma) and interleukins (IL-1 through IL-18) are signaling cytokines that direct immune cell communication, antiviral response, and inflammation. Related entities include tumor necrosis factor (TNF-alpha), colony-stimulating factors (G-CSF, GM-CSF), Janus kinase (JAK) signaling, and T-cell, NK-cell, and macrophage activation assays.

<h2 data-section-id="1p9v7w8" data-start="587" data-end="632">How to choose interferons and interleukins</h2>
&nbsp;
Species and isoform match
Confirm the protocol calls for human, mouse, or rat recombinant protein and the correct isoform (e.g., IFN-gamma vs. IFN-alpha2a, IL-2 vs. IL-15). A mismatched species cytokine will not activate the intended receptor in most cell lines.
&nbsp;
Carrier protein presence
Carrier-free formats (no BSA) are preferred for applications where trace bovine protein could confound downstream assays, such as ELISA development or animal-component-free (ACF) stem cell culture. Carrier-added formats improve stability for general cell culture supplementation.
&nbsp;
Endotoxin level
Endotoxin-free or low-endotoxin (typically &lt;0.1 ng per microgram of protein) preparations matter for immune cell assays, since lipopolysaccharide contamination can independently activate macrophages and skew interleukin readouts.
&nbsp;
Activity verification (bioassay vs. SDS-PAGE)
Look for lot-specific bioactivity data (e.g., ED50 in a proliferation or reporter assay), not only purity by SDS-PAGE, when reproducibility across lots is critical for a multi-month study.
&nbsp;
<h2 data-section-id="1fljvas" data-start="2347" data-end="2372">Specifications context</h2>
&nbsp;
Concentrations for cytokine stimulation assays are typically expressed in ng/mL, with working ranges from 0.1 ng/mL to 100 ng/mL depending on the receptor's sensitivity and the readout (proliferation vs. reporter gene). Specific activity is reported in units/mg or IU/mg for interferons, following international reference standards used to calibrate antiviral potency. As of 2026, labs increasingly request carrier-free, endotoxin-tested lots when cytokines feed into single-cell or multi-omics workflows where background activation must be minimized.
