Product identifiers
US Origin fetal bovine serum treated to significantly reduce lipid content — cholesterol, triglycerides, fatty acids, and lipoproteins. Lipid depletion creates a controlled lipid background that allows researchers to study cellular lipid metabolism, uptake kinetics, and signaling without interference from serum-derived lipids.

Decide once
Five buyer paths and the honest verdict for each. Pick this grade only if your job-to-be-done is in the list.
Yes, this grade. Use lipid-depleted FBS when serum cholesterol, triglycerides, phospholipids, or free fatty acids would mask pathway biology or analytical readout.
Yes, this grade. Residual lipid values are reported by lot so uptake and depletion experiments can be qualified against the actual COA.
Use only if documentation gates. Standard FBS is usually the better value for routine culture. Lipid-depleted FBS carries a typical 40 to 70% premium.
Request a 50 mL sample first. Lipid depletion can change sensitive-cell performance. Qualify the actual lot before scale-up.
Use charcoal-stripped instead. Lipid-depleted FBS targets lipid carriers and residual lipid background. Charcoal-stripped FBS targets lipophilic hormones that drive endocrine assay background. Different chemistry.
