EnGen™ sgRNA Template Oligo DesignerEnGen™ sgRNA Template Oligo Designer can be used to design target-specific DNA oligos for use with the EnGen™ sgRNA Synthesis Kit, S. pyogenes (NEB #E3322).
-
Enzyme FinderUse this tool to select restriction enzymes by name, sequence, overhang or type. Enter your sequence using single letter code nomenclature, and Enzyme Finder will identify the right enzyme for the job.
-
Exo SelectorUse this tool to simplify the process of selecting the appropriate exonucleases for use in your nucleic acid digestion workflows. The tool guides you to product recommendations based on your answers to a few simple questions.
-
Glycan AnalyzerUse this tool to interpret Ultra or High Pressure liquid chromatography (UPLC/HPLC) N-glycan profiles following exoglycosidase digestions.
-
NEB Golden Gate Assembly ToolUse this tool to assist with in silico DNA construct design for Golden Gate DNA assembly. It enables the accurate design of primers with appropriate type IIS restriction sites and overlaps, quick import of sequences in many formats and export of the final assembly, primers and settings.
-
NEB LAMP Primer Design ToolNEB LAMP Primer Design Tool can be used to design primers for your Loop-mediated Isothermal Amplification. Fixed primers can be specified for the design of LAMP primers, and subsequent Loop primers are then designed based on LAMP primer selection.
-
NEBaseChangerNEBaseChanger can be used to design primers specific to the mutagenesis experiment you are performing using the Q5 Site-Directed Mutagenesis Kit. This tool will also calculate a recommended custom annealing temperature based on the sequence of the primers by taking into account any mismatches.
-
NEBclonerUse this tool to find the right products and protocols for each step (digestion, end modification, ligation and transformation) of your next traditional cloning experiment. Also, find other relevant tools and resources to enable protocol optimization.
-
NEBcutter V2.0Use this tool to identify the restriction sites within your DNA sequence. Choose between Type II and commercially available Type III restriction enzymes to digest your DNA. NEBcutter V2.0 will indicate cut frequency and methylation state sensitivity.
-
NEBioCalculatorUse this tool for your scientific calculations and conversions for DNA and RNA. Options include conversion of mass to moles, ligation amounts, conversion of OD to concentration, dilution and molarity. Additional features include sgRNA Template Oligo Design and qPCR library quantification.
