CellFace™ T Cell-Antibody CF04 (Anti-CD19) Conjugate (CAT#: CF-AB-P004)

DataSheet

Product Overview
Description	Employing live cells as therapeutics is a direction of future drug discovery. An easy and robust method to modify the surfaces of cells directly to incorporate novel functionalities is highly desirable. However, genetic methods for cell-surface engineering are laborious and limited by low efficiency for primary cell modification. Creative Biolabs has developed a single-step chemoenzymatic CellFace™ technology platform to transfer bio-macromolecules, such as an IgG antibody (MW∼ 150 KD), to the glycocalyx on the surfaces of live cells. Requiring no genetic modification, our CellFace™ allows for any antibody to be conjugated to the stimulatory surface receptors of immune cells to yield the additive effect of superior tumor targeting to its already potent and off-the-shelf biologic drug payloads. We applied CellFace™ method to construct the CellFace™ T cell-antibody conjugate. The CellFace™ T Cell-Antibody Conjugate is constructed from a T cell line modified with an therapeutic antibody. The modified T cell-conjugate is expected to exhibit novel functions of specific tumor targeting and can be used as a research tool for therapeutic applications.
CellFace™ Platform	Creative Biolabs' CellFace™ Conjugate Technology is a single-step, chemical enzyme-based approach that can quickly engineer cell surfaces in minutes. Through this fast, simple and cost-effective technique, biomacromolecules including proteins (antibodies, antigens) and nucleic acids, as well as small molecule probes such as fluorescent and biophysical probes, are efficiently conjugated without the need for genetic modification of host cells. Fast A unique catalytic enzyme that transfers the conjugate to the cell surface of living cells in a matter of minutes Simple A single-step chemical enzymatic reaction method provides a general method for engineering cells as a research tool and for therapeutic applications Cost-Effective A one-pot approach to combine the synthesis of GDP-fucose derivatives with the subsequent transfer and made this engineering technology practical and cost-effective
