Alzheimer's disease (AD), the most common cause of dementia, was named after its founder, German psychiatrist and neuropathologist Alois Alzheimer. The main symptom of AD is continuously nerve dysfunction, and its main pathogenic symptom is atrophy of cerebral cortex and certain subcortical region. With the progress of the disease, the patients will loss their long-term memory and physical function gradually, and ultimately lead to death. Because AD is becoming a great public health crisis, research programs about the disease are increasing recently. While exploring the mechanism of the disease, three hypotheses had been established. For each of the hypothesis, Cloud-Clone Corp......2014-10-23

CUZD1 is strictly regulated by estrogen in two key reproductive tissues, the uterus and oviduct. Spatio-temporal analyses reveal that CUZD1 mRNA is expressed in a highly stage-specific manner in the uterus and oviduct, and its expression is restricted to the surface epithelium of both of these tissues. Nucleotide sequence analysis of the full-length CUZD1 cDNA indicates that it has an open reading frame of 1821 nucleotides encoding a putative protein of 607 amino acids with a single transmembrane domain and a short cytoplasmic tail. Although the precise function of CUZD1 is not clear, presently, its unique pattern of expression in the uterus and oviduct, and its regulation by estrogen,......2014-04-11

Obesity is the major risk factor for cardiovascular disease, but its mechanism is still not clear. Researchers have proposed two possible hypotheses on obesity-induced diseases: inflammation and increase of oxidative stress. The study of obesity mechanism depends on the study of obesity related bio-markers, and it is very important to find the optimal bio-markers to improve the accuracy of cardiovascular diseases diagnosis. The common used bio-markers are inflammation related bio-markers, for instance, IL6, Adiponectin, Leptin, etc, and oxidative stress related bio-markers, for instance, oxLDL, PPARg, MCP1, etc. Cloud-Clone Corp. has developed a series of quantitative ELISA kits for......2014-03-13

The homology of certain protein in different species is very high, from 95% to 100%. For example, actin beta(ACTb), which is the main component of cytoskeleton microfilament, is widely distributed in various tissues. The protein is expressed by housekeeping gene, and its highly conservative, it shares 100% homology in different mammal species, such as human, rat, mouse, rabbit, pig, bovine, sheep, etc. Based on the characteristics of this kind of protein, we know when an antibody could identify one protein, then it can recognize and combine with this protein in different species. As for this phenomenon, Cloud-Clone Corp. developes a new type of ELISA detection kit with antibody whic......2014-02-08

Calprotectin, usually known as S100A8/A9, is a heterodimeric complex composed by two components, S100A8 and S100A9. These two proteins are calcium- and zinc-binding proteins from the S100 protein family that are released from neutrophils under inflammatory conditions. It has been reported that amounts of S100A8/A9 in blood or extracellular body fluid are increased under many pathological conditions, for instance, rheumatoid arthritis[1], inflammatory bowel diseases[2], viral or microbial infections[3,4], tumors[5], and many inflammatory conditions[6]. Notably, abscess fluids contain more than 1mg/mL of the protein complex[7]. Therefore, the measurement of Calprotectin could be consider......2013-07-25

Gene is the basis of molecular biology. Plasmid construction always includes primer design, template preparation, PCR amplification, fragment recovery, enzyme digestion and ligation, transformation and the final sequencing. The whole process usually takes two to three weeks to complete. However, for each specific gene fragment, many factors should be considered such as restriction enzyme sites. Non-specific bands should also be avoided including Hairpin, False priming and Cross Dimer formed by sense/antisense-primer. In addition, annealing temperature and reagent ratio system should be optimized though repeated tests. RNA extraction and reverse transcription of cDNA are needed for t......2013-07-24
