Staining Protocol Overview
The staining protocol commences with the preparation of chromosomal spreads from patient samples, aiming for an optimal mitotic index. The slides then undergo a rigorous denaturation process to expose the DNA strands, readying them for probe hybridization.
Subsequently, the denatured slides are incubated with the Genebio BCL2L1/CEN 20 Dual Color Probe mixture. The hybridization step allows the labeled DNA strands to attach to their complementary sequences on the chromosomes.
After a predetermined incubation period, stringent washes remove excess and non-specifically bound probe, ensuring that only the intended hybridization signals are retained. The slides are then counterstained to facilitate chromosomal visualization against the backdrop of the probe signals.
Finally, the prepared slides are examined under a fluorescence microscope. This enables the visualization of the dual-color signals that indicate the physical locations of the BCL2L1 gene and the centromere of chromosome 20. Through the differential colors, clinicians can assess the chromosomal architecture and identify any structural anomalies with precision.
