Human RBC precursors are obtained by (i) separating glycophorin A(+) (gly A(+)) cells using a magnetic cell sorting (MACS) technique and by (ii) ex vivo expansion of precursors BFU-E (burst forming unit-erythroid) on methylcellulose semi-solid culture media from mononuclear cells of cord blood.
Sodium carboxymethyl cellulose (CMC) is a cellulose derivative, an ionic cellulose gum, and owing to its unique thickening, suspending, adhesion, and water retention properties, is widely used in various industrial fields.odium carboxymethyl cellulose is generally divided into 3 grades depending on the purity: the food high-purity grade (with a content more than 99.5%), the industrial grade (with a content more than 90%), and crude products (with a content more than 65%).
