Antibodies and processes for preparing the same
Provided herein are various processes for the improved production of antibody producing organisms, antibody producing tissues, antibody producing cells and antibodies. In certain embodiments, provided herein are methods for rapidly producing antibody producing organisms, tissues, cells and antibodies derived from humans, organisms, plants or cells that are genetically altered to over-express certain proteins.
1. A cell comprising an exogenous fusion protein, wherein the fusion protein comprises:
(a) an HIV Tat protein transduction domain sequence;
(b) a MYC polypeptide sequence having a biological activity of MYC, wherein the MYC activity comprises promoting cell proliferation and/or regulating transcriptional activity of MYC responsive genes; and
(c) at least two protein tags, wherein the protein tags comprise a 6-histidine tag and a V5 epitope tag,
wherein the fusion protein is present in the nucleus of a cell, and
wherein the cell is an immune cell or a hematopoietic stem cell.
