All reagents were of analytical quality. Ultrapure (Milli-Q) water (18.2 MΩ cm) from a Direct-Q 3 UV system (Merck Millipore, Darmstadt, Germany) was used for all steps of sample preparation and analysis. Conc. HNO₃ was purchased from Merck (Darmstadt, Germany). A citrate buffer solution (CBS) was prepared as previously described [46 (link)].
Working standards for fluoride (F^–) were prepared from a (100.0 ± 0.5) mg/L-certified standard solution (Thermo Fisher Scientific, Waltham, MA, USA). A Merck-IV-certified ICP multi-element standard solution ((1001 ± 10) mg/L, aluminium) was used to prepare working standards for aluminium (Al). A 0.050 mol/L working solution of sodium fluoride was prepared by dissolving NaF (Merck) in water.
The accuracy of the calibration curve for F^– was checked with another certified F^– standard solution and for Al with an Inorganic Ventures certified-quality standard IV-ICPMS-71A ((10.01 ± 0.04) mg/L, aluminium) (Christiansburg, VA, USA).
Samples were weighed into brown tea filter Cilia size M (Melitta, Minden, Germany). The 0.45 µm polytetrafluoroethylene hydrophobic membrane filters (25 mm diameter) from Machery Nagel (Dueren, Germany) were used for filtration with a 10 mL syringe Chirana (Stará Turá, Slovakia).

Mineral Content Analysis of Feed Samples

The samples of diets offered were dried and ground in a hammer mill to a fineness of 1mm size and analysed for proximate principles [12 ] and fibre fractions i.e., neutral detergent fibre (NDF) and acid detergent fibre (ADF) [13 ]. The feed samples were taken in pre-weighed silica crucibles and oven dried at 80°C for 24 h, decarbonized and ashed at 600°C in a muffle furnace for 3 h. The total ash was digested with 5N HCl over a hot plate for 15 min, cooled and filtered through Whatman filter paper (No. 41) into volumetric flasks. Mineral contents in feed samples were estimated using inductively coupled plasma optical emission spectrophotometer (ICP-OES; Optima 800, Perkin Elmer, Shelton, USA) adopting the operating conditions suggested by the manufacturer [10 (link)]. Mineral standard for each element was prepared from ICP multi-element standard solution (Merck Millipore) to arrive at a concentration of 1000 mg/L (stock solution) except for phosphorus, which was prepared from potassium dihydrogen phosphate (KH₂PO₄). For sample preparation and storage, quartz flasks were used instead of borosilicate to avoid contamination with B.

Antimony Air Sampling Protocol

The environmental air sampling devices were set up at a 120 cm height at worksites and administrative offices to collect the particulates in the air using a 37 mm filter cartridge containing a 0.5 μm PolyVinyl Chloride (PVC) filter. Using a flow rate of 2 L/min, personal samplers (Gillian Instrument Corp., West Caldwell, NJ, USA) were set for the sampling time from 5 to 7 h during work. Filter blanks and field blanks were prepared for quality control and were analyzed together with the samples. The filter in the sampling tube was treated with a mixture of 5 mL of 37% hydrochloric acid and 1 mL of 70% nitric acid, followed by ultrasonic shock for 30 min, and filtered using a Milipore filter membrane with a 0.22 μm pore size. The filtrate was diluted with 1% (v/v) of hydrochloric acid and nitric acid [16 ]. We used ICP-MS (Perkin-Elmer SCIEX ELAN DRC II, Waltham, MA, USA) to determine the antimony concentration in the blanks, samples, and standards (ICP multi element Standard Solution, Merck, Darmstadt, Germany). LOD and LOQ were 4.4 µg and 15 µg, respectively. The spike recovery test of antimony was 84.5%.

Glass and plastic containers used in the study were allowed to stand in a 10% HNO₃ solution overnight and rinsed using ultradistilled water (Milli-Q Millipore 18.2 MΩ·cm). All reagents used in the analysis are analytical or of higher grade. Suprapur nitric acid (65%, w/w), suprapur hydrochloric acid (37%, w/w) and analytical grade hydrogen peroxide (30%, w/w), were purchased from Merck (Germany). All solutions used in the study were prepared using ultradistilled water. ICP multielement standard solution of 1000 mg L⁻¹ supplied by Merck was used after step-by-step dilution. Accuracy and precision of the results of the samples were checked using standard reference material (CRM, DORM-3) supplied from the National Research Council of Canada (CNRC).

Microarray-Based Enzyme Immunoassay for Food Allergen IgG

Check if the same lab product or an alternative is used in the 5 most similar protocols

The microarray-based enzyme immunoassay (M-EIA) utilized for immunological testing detects IgG antibodies against food allergens. Extracted and purified food extracts are applied to a microarray. The RIDA^®CHIP FoodGuide consists of multiple food allergens in each cavity, including two standard rows for quantification and positive and negative controls. Patient samples (capillary blood eluate) were pipetted into wells and incubated, allowing specific IgG antibodies to bind to the corresponding adsorbed food antigens. After washing to remove unbound material, an anti-human IgG antibody conjugated with horseradish peroxidase was added. This conjugate bound itself to human IgG antibodies in the patient sample during reincubation. Unbound conjugate was washed away, and once the substrate was added, an insoluble blue product was formed through the oxidized horseradish peroxidase [31 ]. The amount of blue precipitate was proportional to the antigen-specific antibodies in the serum, detectable photographically. RIDASOFT^® Win.Net Food&Feet A8592 was used to quantify the resulting data, generating comprehensive reports. Calibration was carried out using standard solutions with concentrations between 0.3 and 3 μg/L, prepared from an ICP multi-element standard solution of 1000 mg/L (Merck KGaA, Darmstadt, Germany).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
