Article Title: A Novel mRNA Level Subtraction Method for Quick Identification of Target-Orientated Uniquely Expressed Genes Between Peanut Immature Pod and Leaf
Article Snippet: It can be performed in most conventional laboratories without requiring the purchasing of expensive kits and/or pieces of equipment. .. The highlights of this protocol include (a) its great success for driver preparation and subtractive hybridization using just tiny amounts of mRNAs , when comparing it to most current protocols that require huge amount of mRNAs for the same purpose [ ]. (b) As compared with previously reported protocols that apply paramagnetic oligo (dT) beads as solid base for subtractive hybridization [ , ], streptavidin-coated magnetic beads provide the strongest and irreversible binding capability to immobilize the drivers, which ensures the elimination of hybridized common mRNAs. (c) The protocol does not require PCR cloning for subtractive library construction. .. This is beneficial because it prevents developing subtractive libraries with larger capacities of clones as previously reported [ , , , - ]. (d) There is no need for radioisotopes and/or some related specialized enzymes such as [α-32 P]dCTP [ , ] and terminal transferase [ ].

Article Title: Development and characterisation of nine polymorphic microsatellite markers for Tephrosia calophylla Bedd. (Fabaceae)
Article Snippet: The ligated fragments were enriched through hybridisation with biotinylated dimeric and trimeric nucleotide repeats (CT8 , TC8 , TA8 , TG8 , GC8 , CTT8 , ATA8 and GAA8 ) in three reactions, with incubation at 97 °C for 10 min, followed by 56 °C for 30 min. Streptavidin-coated magnetic beads (New England Biolabs) were used for recovering single-stranded DNA. .. Double-stranded DNA was generated from the enriched DNA fragments via polymerase chain reaction (PCR) using SNX primers.
