FAQs
Frequently Asked Questions (FAQs)
For APOE4 point mutation knockins for Alzheimer's research, can you provide functional validation that the mutation affects protein folding?
We deliver fully sequenced and clonally validated APOE4-mutated cell lines, including protein expression level checks. While functional validation (e.g., folding assays) is not standard, we collaborate with clients to design tailored experiments or recommend downstream partners for phenotypic analysis. Our HepG2 case study highlights our ability to support functional research pipelines.
What specific validation methods do you use to confirm the absence of off-target effects beyond the primary insertion site?
We employ:
●Sanger sequencing to verify target locus integrity.
●PCR-based screening to confirm insert size and orientation.
●Cell viability assays to rule out unintended functional impacts.
While whole-genome off-target analysis is not explicitly mentioned, our stringent QC (100% contamination-free cells and dual mycoplasma/bacterial testing) ensures reliable outcomes.
Do you offer humanized protein expression in mouse cell lines for antibody development projects?
Yes. Our KI services include humanized protein expression in mouse cell lines, enabling applications like antibody development. For example, we generated SR-BI mutant HepG2 cells to study humanized protein interactions in mice. Custom requests for species-specific protein swaps or epitope tagging are available.
Can you perform multiple gene edits simultaneously in the same cell line, and how does this affect validation timelines?
Yes, we support simultaneous multi-gene edits, as demonstrated in our case study delivering a double-point mutation HepG2 cell line. Validation timelines may extend slightly due to additional sequencing and quality checks, but our standardized workflow (including single-cell cloning and multi-step sequencing) ensures thorough characterization. Timelines are project-specific and discussed during quoting.
What is your typical efficiency rate for knockin of large inserts (>2kb) in hard-to-transfect cell lines like primary neurons?
Our Cell iGeneEditor™ system achieves up to 90% editing efficiency for gene knockins (KIs). While insert size and cell type influence outcomes, our optimized homologous recombination protocols and extensive experience with diverse cell types (including neuronal lines like SH-SY5Y and U251) ensure robust results. For hard-to-transfect cells, we conduct pre-experiments to assess feasibility and refine delivery methods. Primary neurons are not explicitly listed in our cell bank, but contact us for custom project evaluations.
