HDR Repair Vectors
Signosis CRISPR HDR Repair-Ready Vectors enable precise knock‑ins and sequence corrections using a flexible two‑vector system. Pair our Cas9 Knockout Vector with our CRISPR HDR Knock-in Vectors, available with prebuilt safe‑harbor donors (mROSA26, hAAVS1) or fully customized templates for any genomic locus.
Principle
Signosis' CRISPR Homology-Directed Repair (HDR) Repair System delivers accurate, template‑driven genome editing through a streamlined two‑vector workflow. A dedicated Cas9 Knockout Vector creates a targeted double‑strand break, while a separate HDR knock-in Vector supplies either a prebuilt or fully customized donor template for precise knock‑ins, tag additions, or sequence corrections. This modular design provides maximum editing flexibility, enabling rapid use of validated safe‑harbor donors (mROSA26 and hAAVS1) while supporting custom HDR designs for any gene or genomic site. Ideal for reporter knock‑ins, protein tagging, functional rescue experiments, and targeted gene correction.
CRISPR HDR gene editing is a two‑step process:
-
Cas9 Knockout Vector (KO Vector)
-
Expresses Cas9 and a locus‑specific gRNA
-
Creates the necessary DNA break at the target site
-
-
HDR knock-in Vector:
-
Delivers a donor template with homology arms
-
Guides precise DNA repair via homology‑directed repair
-
By separating the cut and repair functions into two vectors, the system maximizes editing efficiency, reduces vector size constraints, and supports a wider range of donor template configurations.
Key Features
Validated, Ready-to-use Safe‑Harbor Donor Templates targeting:
-
mROSA26 (mouse)
-
hAAVS1 (human)
Ideal for stable expression, reporter integration, and predictable knock‑ins.
