Fragment Analysis Service

Laragen provides fast and reliable fragment analysis services with an AB3730XL. We have three standard dye sets available from Applied Biosystems: DS-30 (6-FAM, HEX, NED and ROX), DS-31 (6-FAM, VIC, NED and ROX) and DS-33 (6-FAM, VIC, NED, PET and LIZ). ROX and LIZ are used for internal size standards. We will choose different size standards based on your needs.

Fragment Analysis Applications

  • Short tandem repeat (STR)
  • Amplified fragment length polymorphism (AFLP)
  • Terminal restriction fragment length polymorphism (T-RFLP)
  • Multiplex ligation-dependent probe amplification (MLPA)
  • Automated ribosomal intergenic spacer analysis (ARISA)

You can choose the fluorescent labels from three dye sets (DS-30, DS-31 and DS-33) If you have questions about the dye sets, please contact us

If you don't have a size standard included with your samples, we can provide ROX500, LIZ500, LIZ1200 and ROX1500 size standard for your samples.

For sample preparation, samples can be sent either in 8-strip PCR tubes or 96-well plates. Please seal the 96-well plate with caps, foil tape or heat seal tape to avoid possible cross contamination and sample evaporation. Please label the side of tubes or plates, not on the top (seal or caps) of tubes or plates. For 96-well plates, please arrange samples by the columns, not by the rows. No spaces or illegal characters are allowed in the sample name. Allowable characters include: a - z, A - Z, 0 - 9, and hyphens.
