Plasma Protein Storage

Access and Rational use of Plasma Protein Therapies (PPTs)

The protein storage vacuole

Storage proteins are deposited into protein storage vacuoles (PSVs) during plant seed development and maturation and stably accumulate to high levels; subsequently, during germination the storage proteins are rapidly degraded to provide nutrients for use by the embryo. Here, we show that a PSV has within it a membrane-bound compartment containing crystals of phytic acid and proteins that are ch...

Stability of plasma enzymes during storage.

For measurement of plasma enzyme stability, 18 specimens of whole blood, plasma, and serum from normal subjects were stored at different temperatures. Eight enzymes were assayed after different times of storage: acetytcholinesterase, pseudocholinesterase, glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase, lactic dehydrogenase, acid and alkaline phosphatases, and amylase. At _200 ...

Effects of storage time and exogenous protease inhibitors on plasma protein levels.

Plasma biomarker analysis requires intact unbiased starting material. We analyzed the effects on plasma protein profiles of protease inhibitor cocktails and preprocessing storage. Plasma from 12 healthy subjects collected with and without protease inhibitors was prepared immediately and after 2 hours of room temperature storage. The samples were analyzed by a multiplexed enzyme-linked immunosor...

Protein analysis of boar seminal plasma proteins with protective effect during low-temperature storage of spermatozoa

The present study aimed to investigate the effect of different seminal plasma proteins (SPPs) on boar spermatozoa functional characteristics. We investigated the putative protective effect of SSPs on sperm cells motility and velocity, as well as on the integrity of the plasma membrane (PM) during low-temperature storage at 4 °C. SPPs fractions were obtained and purified by gel permeation chroma...
