Cleanrooms, safety cabinets and lot-by-lot quality control
Quick answer
GMP (Good Manufacturing Practice) is the regulator-defined manufacturing standard that keeps every production lot consistent. EHL Bio's first GMP centre was completed in 2015, inspected by Korea's MFDS in 2016, and a second centre opened in 2019, giving a combined 6,000 lots per year. Inside are particle-, temperature- and humidity-controlled cleanrooms, with all cell handling done in biological safety cabinets (BSC).
A cleanroom keeps airborne particle counts below a defined limit while holding temperature and humidity steady so materials and cells stay uncontaminated. EHL's centre had built-in incubators planned from the architectural design stage, cutting unnecessary movement of cells between zones.
The biological safety cabinet protects the sample, the operator and the environment at once. Air entering and leaving passes HEPA filtration, so opening a culture flask or changing medium does not expose the cells to room-air contamination.
When comparing providers, the questions that matter are: where are the cells cultured, is the facility GMP-certified, what release testing is done (viability, bacterial and fungal contamination, mycoplasma, endotoxin), and can you see the certificate of analysis for the exact lot you will receive.
Beyond Korean standards, EHL Bio holds a Japanese CPC licence — the regulatory route for manufacturing specified cell-processed products for medical use — and was among the first in Korea licensed for human cell handling domestically.
Because infused cells cannot be terminally sterilised like a chemical drug, safety rests entirely on the process. GMP is the framework that forces every step to be documented, verified and reproducible.
A lot is one production batch cultured under the same conditions and released together. In autologous systems a lot is normally tied to a single patient.
You should be able to. A compliant provider keeps a lot release summary and should walk the patient through it before infusion day.
Cryostorage in liquid nitrogen can run for many years, provided the facility has continuous temperature monitoring and a clear storage agreement.
