Mouse Anti-Carbofuran monoclonal antibody, clone CAR

Hydrophilic interaction liquid chromatography (HILIC) equipped with an environmentally friendly capillary column was employed to investigate the retention behavior of carbofuran; a polar stationary phase was used as well. Several conditions were conducted to investigate the retention behavior of carbofuran, such as a comparison study TSKgel (R) Amide-80 with another polar column, a comparison study retention behavior of carbofuran on various wavelengths, the water content effect on HILIC mode, the effect of buffer concentration on HILIC mode, and the analytical performance of carbofuran. The results showed that TSKgel (R) Amide-80 exhibited a better performance than other polar stationary phases in carbofuran determination, and observations at wavelengths of 251 and 254 nm showed higher absorbance for carbofuran than others. In addition, the increase of water content and salt buffer concentration in the mobile phase led to a shorter retention time. The recovery of this method was 101 +/- 10.1%, while the limit of detection and the limit of quantification were 0.66 ppm and 2.22 ppm, respectively. Consequently, TSKgel (R) Amide-80 offers a good performance in carbofuran determination, even with the application of 10 cm length column capillary liquid chromatography.

Background: Acetylcholinesterase inhibitor insecticides (AChEIIs) were used extensively in the agrarian region of Anuradhapura for the past few decades. As a result, the region faced a heightened risk of toxicity. Carbaryl, carbofuran, chlorpyrifos, dimethoate, and fenthion were the five hazardous AChEIIs banned from Anuradhapura in 2014. Assessment of post-ban trends in acute poisoning will reveal the impact of the ban. Data on availability and sales of remaining AChEIIs will guide towards preventive measures against related toxicities. Methods: Cross-sectional surveys were conducted at Anuradhapura district of Sri Lanka. Details related to acute AChEII poisoning were sorted from the Teaching Hospital Anuradhapura. Main insecticide vendors in Anuradhapura were surveyed to find information on availability and sales of AChEIIs. Chi-square for goodness of fit was performed for trends in acute poisoning and sales. Results: Hospital admissions related to acute AChEII poisoning have declined from 554 in 2013 to 272 in 2017. Deaths related to acute AChEII poisoning have declined from 27 in 2013 to 13 in 2017. Sales of all five banned AChEIIs had reduced by 100%. Sales of the remaining AChEIIs were declining, except for acephate, phenthoate, and profenofos. However, one of the top selling, most frequently abused carbosulfan, had the highest risk of toxicity. Chi-square for goodness of fit showed a significance (P < 0.001) between the trends of hospital admissions for acute AChEII poisoning and the sales related to AChEIIs. Conclusions: Hospital admissions related to acute poisoning was declining along with the overall sales of remaining AChEIIs, during the post-AChEII ban period. Nevertheless, future vigilance is needed on the remaining AChEIIs to predict and prevent related toxicities.
