Defibrinated Plasma (DFP)
Plasma converted to serum by active and/or passive processes.

Delipidized Plasma/Serum
Either serum (DLS) or plasma (DLP) can be processed to remove endogenous lipids. This helps clarify the serum and reduces turbidity with freeze/thaw cycles. Please note that either delipped product may not behave as a true serum or plasma.

Defibrinated/Delipidized Plasma (DDP)
Plasma converted to serum, with subsequent removal of lipids. This renders the serum optically clear.

Charcoal Stripped Plasma (CSP)
Plasma processed with activated charcoal for global removal of free, low molecular weight hormones. Protein bound hormones are generally not removed by charcoal stripping and can present a problem in some assays.

Charcoal Stripped Serum (CSS)
Serum processed with activated charcoal for global removal of hormones.

Defibrinated/Delipidized Charcoal Stripped Serum (DDCSS)
Plasma converted to serum, with subsequent removal of lipids. It is then processed with activated charcoal for global free hormone removal.

Resin Stripped Serum (RSS)
Serum processed with ion exchange resin for optimal thyroid hormone protein removal. This process is more effective than charcoal stripping for removal of these analytes.

Gamma Depleted
(Universally Depleted) (GDS)
Processed for total immunglobulin removal.

Affinity Purification (AFP)
Serum or plasma processed for specific analyte removal. This is a very selective, but costlier method best when global removal of analytes is not desired.

Ultrafiltration Plasma/Serum
Serum (UFS) or plasma (UPF) processed for protein removal of certain molecular sizes. This optimizes serum or plasma for protein binding studies.

Diafiltration (DIA)
Serum or plasma that is actively dialyzed against buffered solutions for analyte removal and/or addition of certain electrolytes.

Sterile Filtration (SF)
Product is processed through a 0.22 micron absolute filtration scheme for removal of bioburden.
