Abstract

Abstract This invention provides a blood typing training kit comprising a red blood cell model and an antiserum model with no use of human blood in experiments for blood agglutination and in learning of blood typing, the red blood cell model being an easily available granule which can be suspended in water such as agarose bead, Sepharose, cellulose, Sephadex, cellulofine, alginate, tamarind polysaccharide, gelatin, xanthan gum, etc. or the saccharide- or protein-bound form thereof and the antiserum model being lectin, boric acid-containing liquid or immunoglobulin G.
