Is there anybody working on the oxygen mass transfer in cell cultures in a stirred tank bioreactor?

I have been working on cell cultures in stirred tank reactors. I want to know how to calculate the kLa (oxygen mass transfer coefficient) in such cases where we are growing cells inside the...

How do we calculate the kLa for the cell culture, while changing the agitation rate inside the reactor?

Suppose we are growing the cells inside the reactor, we start with a fresh inoculum. How can we calculate the kLa inside the reactor, while changing the agitation rate (RPM). Ca anyone please...

How can one exactly calculate the volumetric mass transfer coefficient in a stirred tank bioreactor once cells start growing inside the reactor?

I am currently working on hydrodynamics of stirred tank reactors for cell cultures and we are calculating the kLa and I want to know how can we exactly calculate kLa once cells start growing...

What is the best method of determining the volumetric mass transfer coefficient while the cells are growing inside the reactor?

I am working on the E.coli cell culture trying to study the impact of rheology on the mass transfer coefficient in a stirred tank reactor. What is the best method of determining the kLa at...

Is there anybody working on the CFD simulation of stirred tank reactors? Please let me know?

I am actually simulating the stirred tank reactor using CFD. I am using the Ansys Fluent to carry out the simulations. I am able to carry out the simulations for the single phase (water). However,...

Which cell line should we use to perform biological dosimetry experiments?

We are preparing some experiments based on irradiating cells under different conditions in order to evaluate the effects in terms of DNA damage, genetic expression, etc. As our project is...

Is it possible for two human neuronal cell lines to have different gene sequence for the same protein?

I am looking at the ATP1A2 (Sodium/Potassium ATPase alpha subunit 2) in two human neuronal cell lines. Expression levels of this protein seems to be almost equal when detected by one antibody....

Is CD44 degraded in lysosome together with hyaluronan after CD44 mediated endocytosis of hyaluronic acid?

Also when RHAMM binds hyaluronic acid, they get internalized, will RHAMM also be degraded? Or both CD44 and RHAMM will be transferred back to the cell membrane? Asking for breast cancer cell line...

Do you need the CMV enhancer before the CMV promotor for a proper function of CMV on the gene that follows?

I'm a student and I have to produce a cell line with a knockin for the NRF2 gene with GFP. I have to put a promotor in front of the GFP because the gene will be too far away from the promotor of...

What could be some reasons why unstimulated monocytes are getting activated?

Im doing PBMC isolation -> CD14+ enrichment using magnetic beads -> stimulation setup. My negative control is just cells in cRPMI but they seem to get activated over and over again.
