Substrate for retaining erythrocytes

Abstract

Abstract 1. Process for the separation of erythrocytes from blood, characterised in that one brings the blood into contact with a substance of the group of compounds of the general formula R1 -Sp-R2 in which R1 and R2 are the same or different and represent -SO3 H, -CO2 H, -NH2 or -OH, especially in the form of their ions, R2 also a nitro, sulphonamide or carboxylic acid amide group or halogen or alkoxy group and Sp an aromatic or heteroaromatic ring system of at least two rings which are either annellated or bound directly or via -CH=CH-, -N=N-, -CR3 =N-, -NR3 -CO-NR4 -, -CR3 R4 -, whereby R3 and R4 signify hydrogen or an alkyl group and the ring systems can possibly also carry further substituents or, when R1 and R2 simultaneously signify -NH2 , also represents an alkylene group with 2 to 10 C-atoms and Primazin Yellow GRL**(R) , Levafix Brilliant Yellow E3G**(R) , Levafix E-R2**(R) , Levafix Gold Yellow EG**(R) , Blancophor REU**(R) , Blancophor RA**(R) , Blancophor BE**(R) , Blancophor BA 267**(R) , Blancophor BBH**(R) , Blancophor RPA**(R) , Blancophor BBU**(R) , Tinopal BV**(R) (C.I. 40630), Tinopal UP**(R) , Uvitex NB**(R) , Uvitex RT**(R) , Uvitex CF**(R) , anthraquinone-2,6-disulphonic acid (Na salt), 2-ethoxy-6,9-diaminoacridine, Primazin Brilliant Yellow 3-GL**(R) , Remazol Yellow FG**(R) , Remazol Yellow G**(R) , Remazol Yellow GNL**(R) , Remazol FGH**(R) , Remazol Brilliant Yellow GL**(R) , Solidazol Brilliant Yellow 4G**(R) , Acid Yellow 38**(R) (C.I. 25135), Acid Yellow 40**(R) (C.I. 18950), Acid Yellow 65**(R) (C.I. 14170), Acid Yellow 76**(R) (C.I. 18850), Acid Yellow 99**(R) (C.I. 13900), Direct Yellow 8**(R) (C.I. 13920), Direct Yellow 27**(R) (C.I. 13950), Direct Yellow 62**(R) (C.I. 36900), Basic Yellow 11**(R) (C.I. 48055), Thiazole Yellow**(R) (C.I. 19540) and Paper Yellow RF**(R) (C.I. 40000), filters simultaneously or subsequently through a filter layer of glass fibres, cellulose, synthetic resin or asbestos fibres and recovers the separated plasma.
