  • SEQUENCE FORMAT – Send your custom sequence(s) by email attachment in an Excel, Word, or FASTA file. Provide a name for each sequence. Please send your email to
  • SEQUENCE SCREENING – Aster can produce many difficult sequences, but there are occasions in which certain repeats and extreme GC content prevent synthesis. Upon receipt, Aster will screen each sequence and let you know if there are any synthesis limitations.
  • CLONING VECTORS – We can assemble your custom sequence into any one of our nine standard cloning vectors for no addition charge. These standard vectors include high-copy plasmids, low-copy-plasmids, and inducible-copy BACs, with your choice of kanamycin resistance, chloramphenicol resistance, or ampicillin/carbenicillin resistance. Aster can also move cloned sequences into a vector of your choice for an additional $100 per sequence.
  • PRODUCT YIELD – Products cloned into a plasmid vector are delivered with a minimum yield of 5 micrograms. Products cloned into a BAC vector are delivered with a minimum yield of 1 microgram.
  • SEQUENCE GUARANTEED - All cloned DNA products are shipped with an accompanying NGS sequencing report confirming sequence accuracy.
