Mechanisms of Tumor Antigen Presentation and Immune Escape
Tumor Antigen Presentation Defects (TAPD) represent a sophisticated escape mechanism where neoplastic cells silence the "master switches" of immunity, such as NLRC5 and CIITA, or physically alter the MHC-I/II groove structure. Research indicates that a high proportion of solid tumors across various experimental models utilize these complex pathways to achieve immune invisibility. Creative Biolabs' service provides a high-resolution analysis of the entire antigen life cycle - from intracellular ERAP-mediated trimming to MHC-II CLIP displacement - ensuring your research targets are rigorously evaluated for visibility to the immune system.

Accurate HLA-LOH Detection
Partnering with Creative Biolabs allowed us to distinguish between genomic antigen loss and processing defects in our lead program. Their high-sensitivity algorithms successfully identified sub-clonal escape mechanisms that standard tools missed. - S**h. Z. -
Pathway Mapping
The inclusion of ERAP1/2 enzymatic analysis facilitated our neoantigen discovery efforts by identifying over-trimmed peptides. This insight prevented us from pursuing several targets that the model could not physically display. - Prof. M***o. K.
FAQs
How does your service differ from standard Whole Exome Sequencing?
Unlike WES which focus only on mutations, we provide functional analysis of processing machinery. We evaluate surface presentation, enzymatic trimming, and epigenetic silencing that standard sequencing often misses.
What is the minimum purity required for results?
We accept diverse research samples. Our advanced bioinformatic deconvolution techniques allow us to adjust for varying purity levels, ensuring high-resolution results even in complex or heterogeneous tissue.
