| Comments： | Restriction digests of the clone give the following sizes (kb): HindIII--5.2; HindIII/XbaI--4.2, 1.2; PstI--5.2; XbaI--5.2; XhoI--5.2. The Ig hinge cysteines were mutated to serine residues during construction to prevent intrachain disulfide bonding. Expresses a soluble derivative of CD28, consisting of the oncostatin M signal sequence, the extracellular portion of CD28, and the hinge, CH2 and CH3 portions of Ig Cgamma1. |
