An improved method for in situ hybridization was developed in order to identify the tissue-specific expression of messenger RNA (mRNA) for the novel extracellular matrix glycoprotein, tenascin, during mouse development. Non-radioactive RNA probes were generated by incorporating digoxigenin-11-UTP instead of conventional isotopic labels. Hybridization of anti-sense probes to complementary mRNAs ...
Although cardiomyocyte death and infarction associated with ischemia-reperfusion are traditionally believed to be induced via necrosis, recent studies implicated apoptotic cell death in ischemic reperfused tissue. To examine whether myocardial ischemic reperfusion injury is mediated by apoptotic cell death, isolated perfused rat hearts were subjected to 15 and 30 min of ischemia as well as 15 m...
Random mutagenesis and selection using phage or cell surface display provides an efficient method for affinity maturation of single chain Fv (scFv) antibodies, thereby improving function in various applications. To investigate the effects of mutation frequency on affinity maturation, error-prone PCR was used to generate libraries containing an average (m) of between 1.7 and 22.5 base substituti...
Pituitary adenylate cyclase activating polypeptides (PACAP27 and PACAP38) are members of the VIP/secretin/glucagon family of peptides and have diverse neuroregulatory effects in sympathoadrenal cell development and function. PACAP peptides regulate rat superior cervical ganglion (SCG) neuron catecholamine and neuropeptide Y content and secretion, and promote sympathoneuroblast survival through ...
A rapid dot blot hybridization assay for the detection of B19 parvovirus DNA in human sera was developed. Small portions of four serum samples were mixed, filtered onto a nylon membrane, and hybridized with a digoxigenin-labeled DNA probe; for each membrane, 380 serum samples could be tested. When a dot was positive by the hybridization assay, the four serum samples dotted together were separat...
We optimized a novel nonradioactive hybridization technique using a cis-platin coupled digoxigenin derivative for direct labeling of mRNA. This new mRNA reporter molecule was applied to cDNA membrane arrays to simultaneously identify expression of hundreds of genes. The sensitivity of this nonradioactive mRNA hybridization technique was comparable to radioactive cDNA labeling on house-keeping g...
Bispecific antibodies (bsAbs) that bind to cell surface antigens and to digoxigenin (Dig) were used for targeted small interfering RNA (siRNA) delivery. They are derivatives of immunoglobulins G (IgGs) that bind tumor antigens, such as Her2, IGF1-R, CD22, and LeY, with stabilized Dig-binding variable domains fused to the C-terminal ends of the heavy chains. siRNA that was digoxigeninylated at i...
The main objective of the present study was to develop an efficient and reliable probe to be routinely used for detection of chromosome 13 copy numbers by interphase FISH. To achieve this, a Yeast Artificial Chromosome (YAC) containing sequences specific for human 13q12 (744D11), was cultured and the whole yeast genomic DNA was extracted. The human insert within the isolated DNA was amplified b...
