Posted by Troy

Therapeutic monoclonal antibodies have the potential to cause an unwanted immune response, resulting in anti-drug antibody production (fennel). Fennel binding to drugs and subsequent formation of the immune complex (ICS) can trigger various responses, depending on the size, concentration, and subclass of Agas. To better understand the impact of Agas on pharmacokinetics, pharmacodynamics, and toxicological profiles, the bioanalysis method was developed to detect ICS between the Immunoglobulin G (IGG) of humans and Agas in biological samples.

Regarding experimental procedures, briefly, the specific ICS of human antibodies and human antibodies that are not bound in biological samples are separated through electrophoresis of original blue polyacrylamide gel (BN-PA-Page). The target fraction is then cut from the gel, followed by the digestion of Trypsin in the gel and liquid chromatography then the spectrometry of the spectrometry (LC-MS / MS) to monitor human specific peptides. This method is able to detect various types of human antibodies with lower detection limits than 10 μg / ml in serum monkeys. The performance of testing for ICS detection is shown using barbed samples, and pre-incubation ICs in the monkey serum are clearly detected.

Taken together, these findings indicate that our method allows semi quantitative analysis to estimate the ratio of human antibodies including IC compared to total antibodies. This method was successfully applied to the study in Vivo using mice, and data helped explain unexpectedly cleaning antibodies due to large IC formation. The combination of ICS separation by BN-PAGE and Human IgG specific peptide detection by LC-MS / MS is a common bioanalytical approach that is useful for Detection of ICS in animals.

The characterization of the eubacterial community by denying the gradient gel electrophoresis (DGGE) and the next generation sequencing (NGS) in the biotrickling deculfurization filter using progressive changes in nitrate and nitrite as the final electron acceptor.

Anoxic biotrickling filters (BTFS) represent the technology with high H2S elimination capacity and removal efficiency which is widely studied for biogas desulfurization. Three changes in the final electron acceptor are made using nitrate and nitrite during the operating period of 520 days. BTF’s anoxic stability and performance is maintained when a significant disruption is applied to a system involving progressive changes in nitrate to nitrite and vice versa.

Here the impact of changes in electron acceptors in the microbial community are characterized by denaturation of electrophoresis (DGGE) gradient gel and the next generation (NGS) sequencing. Both platforms revealed that the community underwent changes during perturbations but was tough because the transfer capacity did not significantly change. Proteobacteria and bacteroides are the main phylum and sulfurimonas and Tiobacillus which are the oxidizing genera-oxidizing-oxidizing (NR-SOB) involved in the biodesulfurization process

Monitoring the plasmid vaccine topology with capillary gel electrophoresis.

Plasmid DNA has been widely used in vaccination as well as in cells and gen therapy. It exists in some isoforms including supercoiled, scelled or open circular and linear forms. Regulatory institutions recommend having more than 80% of supercoiled isoforms for mass release plasmid products; Thus must be analyzed accordingly. The traditional analysis method for Plasmid DNA is Gel Gel Electrophoresis. However, because manual sample loading, visualization, and analysis of manual data, it has limitations in obtaining consistent quantitative results.

A method combining blue native polyacrylamide gel electrophoresis with liquid chromatography tandem-mass spectrometry to detect circulating immune complexes between therapeutic monoclonal antibodies and anti-drug antibodies in animals.

In this brief communication, we introduce a fast, sensitive, and powerful plasmid analysis method using capillary electrophoresis with fluorescence detection of laserinduced (CE-LIF). CE-LIF analysis of the isoform Supercoiled and open circle partners are finished in 20 minutes with excellent sensitivity by using the dye binding the same neon flow. The advantage of this method is indicated by the purity analysis of two large plasmids (7 KB and 10 KB). Sample loading, separation, and completely automatic data analysis display repetition of improved tests and ease of quantization of gel electrophoresis gel agarose degradation.

Molecular typing acinetobacter baumannii which resistant drugs from clinical and environmental specimens in three Iranian hospitals with pulsed field gel electrophoresis.

Multi-Medicine Resistant (MDR) Acinetobacter Baumannii is one of the most important causes of nosocomial infections. The purpose of this study was to identify antibiotic resistance patterns, biofilm formation and clinical relations of clinical and environmental isolates A. Baumannii with the electrophoresis method of field gel pulsed. Forty-three clinical and 26 environmental isolates from MDR A. Baumannii was collected and recognized through 20ne fire. Antibiotic resistance of isolates is assessed by disk diffusion method, and biofilm formation tests are carried out by the microtiter plate method. Field gel electrophoresis (PFGE) is used to assess the genome features of bacterial isolates.

The resistance level of clinical and environmental isolates to antibiotics comes from 95 to 100%. The difference between antibiotic resistance between clinical and environmental isolates is not statistically significant (p> 0.05). The ability of biofilm production reveals that 31 (44.9%), and 30 (43.5%) isolates have strong and moderate biofilm producers activities. Typing PFGGes shows eight different clusters (A, B, C, D, E, F, G, and H) with two significant clusters including A and G with 21 (30.4%) and 16 (23.2%) each -Masing, which consists of 53.6% of all isolates. There is no relationship between biofilm formation and antibiotic resistance patterns with pulsotypes of PFGE.

The results showed that there was a close relationship between environmental and clinical isolates A. Baumannii. Cross contamination is also very important that occurs through daily clinical activities between environmental and clinical isolates. Therefore, to reduce Klonal Contamination MDR A. Baumannii environment and clinical isolates, it is necessary to use strict infection control strategies.
