Invitrogen™ MultiShot™ FlexPlate Mach1™ T1R Competent Cells
MultiShot FlexPlate Mach1 T1R chemically competent E. coli cells are exceptionally fast-growing cloning competent cells pre-aliquoted in a 96-well PCR plate to increase transformation productivity.
MilliporeSigma™ Annexin V-PE Apoptosis Detection Kit
Identifies phosphatidylserine (PS) that translocates from cytoplasmic face of plasma membrane to cell surface during apoptosis.
Invitrogen™ One Shot™ TOP10 Electrocomp™ E. coli
One Shot TOP10 Electrocomp E. coli cells are ideal for high-efficiency cloning and plasmid propagation. Provided at a transformation efficiency of >1 x 1010 cfu/ μg supercoiled DNA, these cells allow for stable replication of high copy number plasmids.
Invitrogen™ One Shot™ TOP10/P3 Chemically Competent E. coli
One Shot TOP10/P3 Chemically Competent E. coli cells are designed for vector transformation encoding the synthetic supF gene (tyrosine tRNA suppressor) and allow high-quality pCDM8, pcDNA1.1 plasmid, or any other supF-containing vector preparation.
MilliporeSigma™ Novagen™ BL21(DE3) Competent Cells
Achieve greater efficiency, reproducibility and convenience with Novagen prepared competent cells. BL21(DE3) is a chemically competent E. coli cell suitable for transformation and high-level protein expression using a T7 RNA polymerase-IPTG induction system.
MilliporeSigma™ Novagen™ BL21(DE3) pLysS Competent Cells
BL21 host strain that expresses T7 RNA polymerase and also encode T7 lysozyme that suppresses basal expression of toxic target proteins prior to induction.
MilliporeSigma™ Novagen™ HMS174 (DE3) Competent Cells
HMS174 strains provide high transformation efficiencies and the recA mutation in a K-12 background. Strain may stabilize certain target genes whose products may cause the loss of the DE3 prophage.
Invitrogen™ Tali™ Calibration Beads
Align and calibrate Tali™ Image-Based Cytometer every three months
Invitrogen™ One Shot™ PIR2 Chemically Competent E. coli
One Shot PIR2 Chemically Competent E. coli cells are for use with vectors that contain the R6Kγ origin of replication (e.g., pUni/V5-His-TOPO for recombination with an Echo cloning system).
MilliporeSigma™ Novagen™ Origami™ 2(DE3) Singles™ Competent Cells
Origami 2 strains have mutations in glutathione reducatase (gor) and thioredoxin reductase (trxB), facilitating proper disulfide bond formation.
Invitrogen™ MultiShot™ Mach1™ T1R Chemically Competent E. coli Cells, 96-well plate
MultiShot Mach1™ T1R Chemically Competent E. coli Cells enable rapid, high-efficiency cloning in an automation-ready 96-well format. Fast-growing and phage-resistant, these cells support same-day transformation and streamlined high-throughput workflows.
Invitrogen™ MultiShot™ Mach1™ T1R Chemically Competent E. coli Cells, 96-tube rack
MultiShot Mach1 T1R Chemically Competent E. coli Cells enable rapid, high-efficiency cloning with flexible workflow capacity. The 96-tube rack format supports same-day transformation, plating, and colony picking for fast, scalable cloning workflows.
Invitrogen™ One Shot™ PIR1 Chemically Competent E. coli
One Shot PIR1 Chemically Competent E. coli cells are for use with vectors that contain the R6Kγ origin of replication (e.g., pUni/V5-His-TOPO for recombination with an Echo cloning system).
MilliporeSigma™ Novagen™ BL21 (DE3) pLysS Singles™ Competent Cells
BL21 strains are the most widely used hosts for protein expression from pET recombinants and have the advantage of being deficient in both lon and ompT proteases.
