Product Details

The therascreen UGT1A1 Pyro Kit is used for genotyping of allele variant *28 and allele variant *6 of the human UGT1A1 gene. The kit contains primers and reagents for amplification of the genes, plus buffers, primers, and reagents for genotyping in real time using Pyrosequencing technology on the PyroMark Q24 system.

Principle

The therascreen UGT1A1 Pyro Kit is used for genotyping of allele variant *28 (for distinguishing between 6 and 7 TA repeats) and allele variant *6 (for distinguishing between G and A genotype) of the human UGT1A1 gene. The UGT1A1 gene encodes the enzyme UDP-glucuronosyltransferase, which catalyzes the conversion of xenobiotic and endogenous compounds into water-soluble molecules that can be excreted. Genetic polymorphisms found in the human UGT1A1 gene are associated with reduced UGT1A1 expression and activity. The most common polymorphisms occur in the UGT1A1 promoter region that contains several repeating TA elements (UGT1A1*28), and as a non-synonymous coding variant G71R (UGT1A1*6) in exon 1.

Procedure

The kit consists of two assays: one for genotyping of allele variant *28 and the second for genotyping of allele variant *6. The two regions are amplified separately by PCR and sequenced through the defined region (see figure " Illustrations of the therascreen UGT1A1 assays"). Sequences surrounding the defined positions serve as normalization and reference peaks for genotyping and quality assessment of the analysis.

After PCR using primers targeting allele variants *28 and *6, the amplicons are immobilized on Streptavidin Sepharose High Performance beads. Single-stranded DNA is prepared, and the corresponding sequencing primers anneal to the DNA. The samples are then analyzed on the PyroMark Q24 system.

Applications

The therascreen UGT1A1 Pyro Kit for genotyping of allele variant *28 and allele variant *6 of the human UGT1A1 gene (see figures " Pyrogram trace obtained after analysis of a sample with –/– (TA6/TA6) genotype when analyzed for allele variant *28", " Pyrogram trace obtained after analysis of a sample with –/TA (TA6/TA7) genotype when analyzed for allele variant *28", and " Pyrogram trace obtained after analysis of samples with a G/G genotype when analyzed for allele variant *6"). This kit enables genotyping analysis applicable to several fields of clinical applications, such as diagnostic evaluation, clinical research, and pharma/biopharma testing.

FAQ

Can PyroMark Gold reagents be vortexed?
Reconstiuted enzyme and substrate of PyroMark Gold Reagents, should not be vortexed since this could lead to conformational changes which affect the activity.
