24sure cytochip

Manufactured by Illumina
Sourced in United Kingdom

The 24Sure Cytochip is a laboratory equipment product designed for cytogenetic analysis. It is a microarray-based platform that enables the detection of chromosomal aberrations and abnormalities. The core function of the 24Sure Cytochip is to provide a comprehensive and accurate assessment of the entire chromosome complement in a single analysis.

Microarray-CGH Analysis of Single Cells

Microarray-CGH analysis was undertaken according to our previously validated protocol using 24Sure Cytochip (Illumina, Cambridge, UK) (see online supplementary tables S5 and S6). Lysis and whole genome amplification of single cells biopsied from embryos were achieved using the SurePlex kit (Illumina). The entirety of this procedure took place according to the manufacturer's instructions. The fluorescence labelling system (Illumina) was used for the labelling of the amplified ethylenediaminetetraacetic acid-Tris (TE) samples and also for labelling a commercially available reference DNA (Illumina). Test TE samples were labelled with Cy3 while the reference 46,XY DNA was labelled with Cy5. Test and reference DNAs’ co-precipitation, their denaturation, array hybridisation and the posthybridisation washes all took place according to protocols provided by the manufacturer. The hybridisation time was 16 h.
A laser scanner (InnoScan 710, Innopsys, Carbonne, France) was used to analyse the microarrays after washing and drying. The resulting images were stored in TIFF format file and examined by the BlueFuse Multi analysis software (Illumina). Chromosome profiles were examined for gain or loss with the use of a 3× SD assessment.

Clumps of cells were harvested from ePNT blastocysts for whole genome amplification followed by microarray-CGH analysis according to a previously validated protocol using 24Sure Cytochip (Illumina, Cambridge, UK). Cells were obtained from the TE, ICM or both. Lysis and whole genome amplification was performed using the SurePlex kit (Illumina) according to the manufacturer’s instructions. Samples from ePNT blastocysts were labelled with Cy3 while a commercially available reference 46,XY DNA was labelled with Cy5 (Illumina)32 (link). A laser scanner (InnoScan 710, Innopsys, Carbonne, France) was used to analyse the microarrays after washing and drying. The resulting images were analysed using BlueFuse Multi analysis software (Illumina).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
