Peptide Microarray Based Selection

Immune checkpoint molecules are critical in preventing autoimmunity and regulating the immune response. Blocking these immune checkpoints allows anti-tumor activity to resume and is among the most promising approaches to activating therapeutic anti-tumor immunity. Creative Biolabs is a leading service provider that focuses on immune checkpoint peptide drug discovery and development. Professional technical scientists and abundant experience in immune checkpoint peptide development make Creative Biolabs a perfect partner to help our clients' research in the immune checkpoint therapy field.

Peptide Microarray

Peptide microarray is also called peptide chip which displays the target peptides on a solid surface (often a glass or plastic chip). This platform delivers full compatibility of the chips based on overlapping peptide libraries (or non-overlapping peptide libraries) of your target protein or your target proteins by utilizing a flexible peptide synthesis technology. Peptide microarrays and phage technologies can be employed to generate peptide antagonists based on the precise epitopes of antibodies of checkpoint molecules.
