Adaptors and Primers for Library Prep

Adaptors and Primers are an essential component of your NGS sample prep. NEBNext Oligos offer flexibility in multiplexing with a wide range of highly pure index primers, available in unique dual, dual, and single index-primer formats. NEBNext adaptors are designed to optimize yield while minimizing adaptor-dimer formation, and the NEBNext Adaptor, with its unique hairpin-loop structure, offers high ligation efficiency.  

The EM-seq™ Adaptor was optimized for use with NEBNext’s Enzymatic Methyl-seq protocol, a gentler alternative to the harsh sample processing in bisulfite sequencing, and is also compatible with bisulfite sequencing workflows.

NEBNext Oligos are supplied separately from NEBNext Library Prep Kits (except for the Small RNA and EM-seq Kits) to provide workflow flexibility.

NEBNext Oligos currently enable multiplexing of up to 384 unique dual indexed reactions, up to 384 dual indexed reactions (using combinatorial indexing), and up to 144 single indexed reactions. For additional information, refer to the NEBNext Multiplex Oligos Selection Chart.
