Giemsa-stained metaphases were captured on a Zeiss Axio Imager Z2 microscope equipped with an automatic Metafer-MSearch scanning platform and a CoolCube 1 b/w digital camera (MetaSystems, Altlussheim, Germany). Metaphases stained with C-banding and in situ hybridization techniques were captured with a Provis AX70 fluorescence microscope equipped with a DP30BW digital camera (Olympus, Tokyo, Japan). All images were acquired in black and white, and later processed using DP Manager imaging software (Olympus, Tokyo, Japan).

Chromosome Analysis and Karyotyping Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
At least 50 metaphase spreads per individual were analyzed to confirm the diploid chromosome number (2n), karyotype structure, and FISH results. Giemsa-stained preparations were analyzed under Axio Imager Z2 microscope (Zeiss, Oberkochen, Germany), equipped with an automatic Metafer-MSearch scanning platform. Photographs of the chromosomes were captured under 100 × objective using CoolCube 1 b/w digital camera (MetaSystems, Altlussheim, Germany). The karyotypes were arranged using Ikaros software (MetaSystems, Altlussheim, Germany). Chromosomes were classified according to their centromere positions,98 modified as metacentric (m), submetacentric (sm), subtelocentric (st), or acrocentric (a). FISH preparations were inspected using an Olympus BX53 epifluorescence microscope (Olympus, Tokyo, Japan), equipped with an appropriate fluorescence filter set. Black-and-white images were captured under 100 × objective for each fluorescent dye with a cooled DP30BW CCD camera (Olympus) using Olympus Acquisition Software. The digital images were then pseudo-colored (blue for DAPI, red for Cy3, green for FITC) and merged in DP Manager (Olympus). Composed images were then optimized and arranged using Adobe Photoshop CS6.

Giemsa Staining and C-banding for Karyotyping

Check if the same lab product or an alternative is used in the 5 most similar protocols
The slides were stained with 5% Giemsa solution. Selected metaphases were captured using a Zeiss Axio Imager Z2 (Zeiss, Oberkochen, Germany), equipped with a Metafer-MSearch automatic scanning platform (MetaSystems) and CoolCube 1 b/w digital camera (MetaSystems). Karyograms were prepared using the Ikaros karyotyping platform (MetaSystems). At least 10 metaphases per individual were studied. We performed C-banding stain to detect heterochromatin distribution according to the protocol of Sumner [46 (link)]. The slides were first treated with 0.2 N HCl for 30 min at room temperature, then with prewarmed 5% Ba(OH)2 for 10 min at 45 °C and finally in 2× SSC for 1 h at 60 °C. Subsequently, the slides were washed with distilled water, air-dried and stained with Fluoroshield mounting medium with DAPI stain (Sigma-Aldrich).

Metaphases from species with undescribed karyotypes were stained with 8% Giemsa solution. Selected metaphases were captured using a Zeiss Axio Imager Z2 (Zeiss, Oberkochen, Germany), equipped with a Metafer-MSearch automatic scanning platform (MetaSystems, Altlussheim, Germany) and CoolCube 1 b/w digital camera (MetaSystems, Altlussheim, Germany). Karyograms were prepared using the Ikaros karyotyping platform (MetaSystems, Altlussheim, Germany). At least 10 metaphases per individual were studied.

The Giemsa-stained slides were scanned with an Axio Imager Z2 microscope (Zeiss, Oberkochen, Germany) equipped with Metafer-MSearch scanning platform and a CoolCube 1 b/w digital camera (MetaSystems, Altlussheim, Germany). The karyograms were constructed in the program Ikaros (MetaSystems). The photos of slides stained by DAPI (slides from C-banding and FISH experiments) were taken by a Provis AX70 microscope (Olympus, Tokyo, Japan) equipped with a DP30BW camera (Olympus). The photos were subsequently processed in DP Manager (Olympus).

Mitotic chromosomes were examined by Olympus BX53 epifluorescence microscope and Axio Imager Z2 microscope equipped with CCD camera (DP30W Olympus) and CoolCube 1 b/w digital camera (MetaSystems, Altlussheim, Germany), respectively. Axio Imager Z2 epifluorescence microscope is equipped by Metasystems platform for automatic search, capture and image processing. Meiotic chromosomes were analysed using Olympus BX63 microscopes equipped with standard fluorescence filter sets, and sCMOS camera (Prime95B Teledyne Photometrics) using CellSense Dimension software (Olympus). The IKAROS imaging program (Metasystems, Altlussheim, Germany) were used to analyse grey-scale images. The captured digital images from FISH experiments were pseudocoloured (blue for DAPI, red for Alexa-594, green for Alexa-488) and superimposed using Microimage and Adobe Photoshop software, version CS5, respectively. Microphotographs were finally adjusted and arranged in Adobe Photoshop CS6 software.

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.
