The Distribution of Reagins in the Serum Protein Fractions Obtained by Continuous Zone Eeectrophoresis

Human reagins: appraisal of the properties of the antibody of immediate-type hypersensitivity.

“…The most notable of these is penicillin, and its derivatives formed in the body (233). Even heavy metals occasionally stimulate specific reagin formation as determined by PK tests (41).…”

“…However, for storage in serum they are usually quite stable. They can be stored frozen at -20 C (325) or at -10 C for 6 months (41) without appreciable loss of activity in the serum. Even refrigerator storage over many months (146,371) or even up to 4 years (69) produces little or no loss.…”

Automatic Operations in Analytical Chemistry

“…The technique of electrophoresis (33,84,66,182) has enabled continuous separations, otherwise impossible or inefficient by normal chromatographic techniques. Further modifications involving improved temperature control and pH control have been described by Adamik (1) and Holdsworth (117).…”

Biochemical Analysis

“…Modified apparatus of the same type has been described (58, 116). The technically difficult apparatus described by Svensson and Brattsten (132) continues in use for the fractionation of serum proteins in quantity (13,16,17). This apparatus employs a vertical tank filled w-ith fineglasspowder, w-ith careful delivery-rates of buffer into and out of the tank.…”
