To better understand emerging adults’ perceptions of family interactions and value transmission to the next generation, we examined Hmong American emerging adults’ reflections on their parents’ parenting. Participants discussed what parenting practices they would do differently and others they hoped to emulate with their future adolescent children. Thirty Hmong American emerging adults (18-25 years; M = 21.2 years; 50% female) participated in interviews that focused retrospectively on the parent–adolescent relationship. Results revealed that emerging adults wanted to parent differently in three ways: less pressure about education, fewer restrictions, and more open communication. Emerging adults imagined being a similar
parent in four ways: promoting education, promoting life values, giving
guidance, and offering love and support. The findings highlight parenting practices that Hmong American emerging adults plan on transmitting (and not transmitting) to their own children, offering a glimpse into the type of parents the emerging adults may become.
Monoclonal antibodies are universal binding molecules and are widely used in biomedicine and research. Nevertheless, the generation of these binding molecules is time-consuming and laborious due to the complicated handling and lack of alternatives. The aim of this protocol is to provide one standard method for the generation of monoclonal antibodies using hybridoma technology. This technology combines two steps. Step 1 is an appropriate immunization of the animal and step 2 is the fusion of B lymphocytes with immortal myeloma cells in order to generate hybrids possessing both parental functions, such as the production of antibody molecules and immortality. The generated hybridoma cells were then recloned and diluted to obtain stable monoclonal cell cultures secreting the desired monoclonal antibody in the culture supernatant. The supernatants were tested in enzyme-linked immunosorbent assays (ELISA) for antigen specificity. After the selection of appropriate cell clones, the cells were transferred to mass cultivation in order to produce the desired antibody molecule in large amounts. The purification of the antibodies is routinely performed by affinity chromatography. After purification, the antibody molecule can be characterized and validated for the final test application. The whole process takes 8 to 12 months of development, and there is a high risk that the antibody will not work in the desired test system.
Leukotriene B4 as an inflammatory mediator is an important biomarker for different respiratory diseases like asthma, chronic obstructive pulmonary disease or cystic lung fibrosis. Therefore the detection of LTB4 is helpful in the diagnosis of these pulmonary diseases. However, until now its determination in exhaled breath condensates suffers from problems of accuracy. Reasons for that could be improper sample collection and preparation methods of condensates and the lack of consistently assay specificity and reproducibility of the used immunoassay detection system. In this study we describe the development and the characterization of a specific monoclonal antibody (S27BC6) against LTB4, its use as molecular recognition element for the development of an enzyme-linked immunoassay to detect LTB4 and discuss possible future diagnostic applications.
