The XA TriScore (X/Y/21) mix of specific probes allows detecting copy number variations for chromosomes X, Y, and 21. The probe mix is composed of repetitive sequences which hybridize to the centromeric region of chromosomes X in blue (aqua) and Y in green. The orange labeled probe hybridizes to a region at 21q22 including the DSCR4 (Down syndrome critical region 4).
Probe maps are created in accordance with the intended purpose of the product. Solid colored bars do not necessarily indicate that the probe fully covers the indicated genomic region. Therefore, caution is advised when interpreting results generated through off-label use. Probe map details based on UCSC Genome Browser GRCh37/hg19. Map components not to scale. Further information is available on request.
Numerical aberrations of autosomes 13, 18, 21, and sex chromosomes X and Y account for 95% of birth defects in newborns. FISH applied to uncultured amniocytes provides a method to identify those aberrations much faster than conventional chromosome analysis. It has become a standard to provide preliminary results for the detection of anomalies in less than 12 hours.
Duplications of chromosome bands 21q22.13-q22.2 have been shown to define the smallest region implicated in the causation of Down syndrome. Repetitive sequences around the centromeric region of the X and Y chromosomes can reliably determine Klinefelter syndrome (47,XXY), Triple-X syndrome (47,XXX), Turner syndrome (45,X0), and 47,XYY. This probe also allows to differentiate male fetal cells from maternal cells in blood contaminated amniocyte samples.
XA TriScore (X/Y/21) hybridized to lymphocytes. Two aberrant interphases (47,XY,+21) are shown.
Normal Cell Male:
One green (1G), two orange (2O), and one blue (1B) signal.
Normal Cell Female:
No green (0G), two orange (2O), and two blue (2B) signals.
Aberrant Cell Male:
Trisomy 21
One green (1G), three orange (3O), and one blue (1B) signal.
Aberrant Cell Female:
Trisomy 21
No green (0G), three orange (3O), and two blue (2B) signals.

MetaSystems proudly announces the opening of our first subsidiary in the Southern hemisphere. The new office is located in Buenos Aires, Argentina and bears the name MetaSystems Latinoamérica SAS (MetaSystems LatAm). The foundation has been the response to the growing demand on technical knowledge and 'know how' experienced in the last years all over the Latin American territories. MetaSystems LatAm takes care for the organization of sales, support, and customer relation activities in all countries in Latin America. It will manage distributor companies and contacts in the region, and it will facilitate communication between end-users, distributors and headquarters in Germany.
MetaSystems Workshop in Dehradun, India
A “Hands-on Workshop on FISH and its application in Pathology and Clinical Medicine” was organized by MetaSystems and Department of Pathology, Himalayan Institute of Medical Sciences (HIMS) to demonstrate the applications of FISH in hematological malignancies and solid tumors.
