Dibutyl phthalate
DBP is an important plasticizer that enhances the utility of some major engineering plastics, such as PVC. Such modified PVC is widely used in plumbing for carrying sewerage and other corrosive materials. [3] Degradation [ edit] Hydrolysis of DBP leads to phthalic acid and 1-butanol. [4] Monobutyl phthalate (MBP) is its major metabolite. [5]
Cross-Reactivity of Drug-Dependent Antibodies in Patients
Cross-reactions, many quite strong (S) were observed among DDAbs specific for drugs in both structural groups (Tables 1 and 2). Particularly noteworthy were cross-reactions of the 19 Group 1 DDAbs with ampicillin (6) and penicillin (6) (Table 1) and of the 14 Group 2 DDAbs with cefepime (6), ceftizoxazole (6) and ceftriaxone (3) (Table 2).

Blood biomarkers of vitamin D status | The American Journal
Most circulating 25 (OH)D and 1,25 (OH) 2 D is transported in the circulation bound to DBP (80–90%) and to albumin (10–20%). A very small fraction [0.02–0.05% of 25 (OH)D and 0.2–0.6% of total 1,25 (OH) 2 D] remains free or unbound ( 7 ). Thus, under physiologic conditions, nearly all circulating vitamin D compounds are protein bound.
- Can a surrogate analyte be used to determine DBP in hexane samples?
- Standard addition method or using artificial matrices reduce the precision and accuracy of the results. In this study a surrogate analyte approach that is based on using deuterium labeled analyte (DBP-d4) to construct the calibration line was applied to determine DBP in hexane samples.
- What is the most important challenge in DBP analysis?
- Considering the ubiquitous nature of DBP, the most important challenge in DBP analyses is the contamination of even analytical grade organic solvents with this compound and lack of availability of a true blank matrix to construct the calibration line.
- What is dibutyl phthalate (DBP)?
- [Google Scholar] Articles from Iranian Journal of Pharmaceutical Research : IJPR are provided here courtesy of Brieflands Dibutyl phthalate (DBP) is a phthalic acid ester and is widely used in polymeric products to make them more flexible. DBP is found in almost every plastic material and is believed to be persistent in the environment.
- How to determine DBP in different matrices?
- Various analytical methods have been applied to determine DBP in different matrices. Utilizing DBP as a plasticizer or dispersing agent in various products makes it to be easily detectable in almost all of the analytical grade solvents and materials that are commonly used for extraction and cleanup procedures in analytical methods.
- Can RDBP be used as coating antigens for DBP-IgM ELISA?
- Purified rDBPs were used as coating antigens (0.25 µg/mL) for the ELISA assay. For DBP-IgM ELISA, 96-well microtiter plates (Costar, Acton, MA) were coated with 25 ng purified Ad5 rDBPC per well at 4°C overnight.
- What is HAdV nonstructural protein DBP?
- The HAdV nonstructural protein DBP is an antigenic protein that could serve as an alternative common antigen for adenovirus diagnosis. Viral structural proteins, which generally elicit strong host immune responses, have been widely used in vaccine and diagnostic reagent development.
