Growth of Ibaraki virus in suspension culture of HmLu-1 cells

The established hamster lung cell line, HmLu-1 cells could grow in a suspended state. The initial cell count, 40 X 10(4)/ml, increased to 200 X 10(4)/ml on the 4th day of culture. The suspension culture of HmLu-1 cells was proved satisfactory for propagation of Ibaraki virus. The viral titer reached a maximum of 10(6.75) TCID50/0.1 ml. The input multiplicity ranging from 0.003 to 3.0 exerted no influence on the final yield of the virus. The optimal pH value of initial culture ranged from 6.8 to 7.6. In comparison of virus yield per cell among the suspension culture and two methods of monolayer culture in stationary and rolling condition, there was no noticeable difference in it among the three methods. The cell population per unit volume was the largest and, therefore, virus titer in the culture fluid the highest in the suspension culture of the three methods.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.
