DL39 (DE3) Chemically Competent Cells - 6x200µl

Intact Genomics chemically competent DL39 (DE3) E. coli cells are specific for transformation and protein expression in order to uniformly and specifically label :e.g. phenylalanine or leucine residues. DL39 (DE3) can also be used to reduce NMR cross-labeling via transaminase activity for valine, leucine, isoleucine, aspartate, phenylalanine, tyrosine and tryptophan residuesProduct Includes:DL39 (DE3) competent cellspUC19 control DNARecovery medium
