Why activated CAR-Jurkat cell could not kill targets?

Previously when I co-coluture anti-CD19(FMC63) CAR-Jurkat with Raji with E:T=5:1, Jurkat can eliminate Raji in 24h. However, when I test another CAR construct, although I can dectect totally CD69...

Does continues partial charging/discharging do any harm to the BESS performance and degradation?

For a grid connected BESS (lets say 100 MW/200 MWh system, LFP battery), if we charge the BESS in such a way that whenever we can access power from the solar that will charge the BESS. Hence it...
