Development of antibodies to human embryonic stem cell antigens

BMC Dev Biol. 2005 Nov 29;5:26. doi: 10.1186/1471-213X-5-26.


Background: Using antibodies to specific protein antigens is the method of choice to assign and identify cell lineage through simultaneous analysis of surface molecules and intracellular markers. Embryonic stem cell research can be benefited from using antibodies specific to transcriptional factors/markers that contribute to the "stemness" phenotype or critical for cell lineage.

Results: In this report, we have developed and validated antibodies (either monoclonal or polyclonal) specific to human embryonic stem cell antigens and early differentiation transcriptional factors/markers that are critical for cell differentiation into definite lineage.

Conclusion: These antibodies enable stem cell biologists to conveniently identify stem cell characteristics and to quantitatively assess differentiation.
