A bacterial transformation template that adapts to your lab's plasmids.

This bacterial transformation template ships configured for heat-shock transformation of chemically competent E. coli (DH5α) with a high-copy cloning vector, using ampicillin selection on LB agar plates. The 10-step protocol covers thawing competent cells on ice, adding plasmid DNA, the 30-minute incubation, the 42°C heat shock, recovery in SOC at 37°C, plating dilutions, overnight incubation, and the next-day colony count and pick.

Structured fields capture sample, transformation conditions, and recovery and plating metadata in typed inputs (competent cell strain, plasmid identity and concentration, antibiotic and concentration, heat-shock time and temperature, recovery medium and time, plating volume, blue/white screening reagents), so the values are queryable across transformations instead of buried in free text. Plasmids and competent cells link to the ELabELN inventory so lot numbers, glycerol stock locations, antibiotic resistance markers, and stock levels flow into the experiment record without manual entry. The spreadsheet editor records the per-plate colony count, transformation efficiency in CFU per microgram of input DNA, and the colony picks selected for downstream verification.

The template is intended as a tested baseline for academic and life sciences research labs running molecular cloning, plasmid amplification, expression construct preparation, or any workflow that introduces foreign DNA into a bacterial host. Configure the strain, swap the plasmid, change the selection marker, or adjust the heat-shock and recovery parameters to match the construct your lab actually runs. ELabELN's tamper-evident audit trail captures every edit, every step check-off, and every electronic signature, so the resulting record supports reproducibility documentation, multi-PI collaboration on shared cloning projects, and FDA 21 CFR Part 11 review when the lab's quality system requires it.
