IMPROVED METHODS FOR PREPARING HIGHLY ACTIVE APRIL LIGAND POLYPEPTIDES

摘要

The present invention relates to improved methods for producing biologically active truncated APRIL ligand polypeptides and analogs thereof. The invention further relates to truncated APRIL ligand polypeptides and analogs thereof that retain a high biological activity and may be isolated in high yields, as well as the nucleotide sequences that encode the truncated APRIL ligand polypeptides and analogs thereof. The invention also relates to compositions of the biologically active truncated APRIL ligand polypeptides and analogs thereof. The invention further relates to the use of the biologically active truncated APRIL ligand polypeptides and analogs thereof in promoting cell proliferation.
