Frequently Asked Questions
What molecular biology tools does Assay Genie offer?
Our molecular biology range spans PCR & qPCR reagents (including high-fidelity polymerases), DNA assembly and TA cloning kits, site-directed mutagenesis and ligation reagents, rapid mycoplasma detection and elimination, enzyme-activity assays, reporter-gene assays and apoptosis reagents — all designed to support accurate, dependable results.
How does a high-fidelity polymerase compare to standard Taq?
High-fidelity polymerases carry proofreading (3′→5′ exonuclease) activity that corrects misincorporated bases during amplification. Our Genie Fusion Ultra High-Fidelity DNA Polymerase delivers up to 53× lower error rates than standard Taq, making it well suited to cloning, sequencing and any application where sequence accuracy is critical.
What is the difference between TA cloning and DNA assembly cloning?
TA cloning ligates a PCR product into a vector using complementary single-base A/T overhangs and is fast and straightforward for inserting amplicons. DNA assembly (seamless) cloning joins one or more fragments at defined junctions without scar sequences, which is ideal for multi-fragment constructs and precise vector design. Assay Genie offers rapid kits for both approaches.
How does the Rapid Mycoplasma Detection Kit work?
The kit uses a PCR-based assay to detect mycoplasma contamination in cell-culture samples with high sensitivity and a fast turnaround, so you can confirm culture cleanliness before proceeding with downstream experiments. Detection kits can be paired with elimination reagents to clear confirmed contamination.
What is site-directed mutagenesis used for?
Site-directed mutagenesis introduces specific, intended changes — point mutations, insertions or deletions — into a DNA sequence. It is widely used to study gene and protein function, engineer enzyme variants and create disease-relevant mutations for research. Our GenieClone DNA Assembly Site-Directed Mutagenesis Kit streamlines the workflow.
How quickly are products delivered?
Molecular biology kits and reagents typically ship within a 7–10 business day lead time after manufacture. Orders can be placed online, by email, through your procurement system or via your local distributor.
