We provide a wide range of antibiotic susceptibility testing services such as Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) tests in accordance with the guidelines issued by the Clinical and Laboratory Standards Institute using broth micro dilution, broth macro-dilution, disk diffusion and agar dilution methods.
The MIC testing services for New Chemical Entity (NCE) helps determine the lowest concentration of an antimicrobial agent that prevents visible growth of a microorganism under defined test conditions.
We use the MIC values to evaluate the activity of new antimicrobial agents and to determine the NCE’s susceptibilities of microorganisms. MIC is considered as the ‘gold standard’ for determining the susceptibility of organisms to antimicrobials and is therefore used to judge the performance of all other methods of susceptibility testing.
Cultured microbes are incubated with the NCE at various concentrations and measured for the results using agar dilution or broth dilution methodology to determine the MIC endpoint. Agar dilution involves incorporating different concentrations of the antimicrobial substance into agar medium followed by the application of a standardized number of cells to the surface of the agar plate. For broth dilution, we often determine it in 96-well micro titer plate format, where microorganisms are inoculated into a liquid growth medium in the presence of different concentrations of an antimicrobial agent. Growth is assessed after incubation for a defined period of time (16–20 hours).
Susceptibility testing is typically conducted using organisms that contribute to an infectious process warranting antimicrobial chemotherapy. Several microorganisms such as aerobic or anaerobic bacteria, yeasts can be tested based on the requirement.
The MBC testing services help determine the lowest concentration of an antimicrobial agent required to achieve bactericidal killing defined at 99.9% reduction in the initial inoculum. We chose it by sub-culturing broth dilution concentrations that inhibit the growth of a bacterial organism i.e. concentrations at and above the MIC. The broth dilutions are streaked onto agar surface and incubated for 24 to 48 hours. MBC is the lowest broth dilution of antimicrobial that prevents the growth of the organism on the agar plate. Failure of the organism to grow on the agar plate implies that all viable microorganisms have been eliminated.

An effective anti-tumor immune response in human is marked by presence of T cells reactive against neoantigens. Neoantigens are HLA-bound unique peptides arise from tumor-specific somatic mutations. Neoantigens are highly immunogenic because they are not present in normal tissues and hence bypass central thymic tolerance. The success of immune checkpoint blockade...
Read MoreGenomics plays a vital role in identifying which gene is associated with a specific disease. A gene called CNOT1 is for example known for it's effect on brain development and for impairing memory and learning. Despite the great promise genomics provides in understanding the disease, genes are not the best drug targets....

Read MoreIntroduction: Any new chemical entity (NCE) needs to undergo various stages of development such as preclinical and clinical trials before drug product is approved by regulatory agencies and available for patient. Formulations developed during early phases are simple formulations to enable phase appropriate studies like screening, dose ranging, toxicological and d...

Scalable alternate end-game strategies for the synthesis of the anti-COVID drug molecule Nirmatrelvir (1,PF-07321332) have been described. The first involves a direct synthesis of 1 via amidation of the carboxylic acid 7 (suitably activated as a mixed anhydride with either pivaloyl chloride or T3P) with the ...
