In the present study, polymerase chain reaction–restriction fragment length polymorphism (PCR–RFLP) analysis was developed to identify 5 species (Trichinella spiralis, Trichinella britovi, Trichinella nativa, Trichinella nelsoni and Trichinella pseudospiralis) and 3 phenotypes of uncertain taxonomic status (Trichinella T5, T6, and T8). Eleven restriction endonucleases were used to restrict 3 DNA fragments (1) a 2800 bp fragment of the 43 kDa excretory–secretory (E–S) protein gene, (2) a 1250 bp fragment amplified with the primer pair SB147A and (3) a 372 bp fragment amplified with the primer p

PCR-RFLP technique was developed for identification and differentiation among chicken?s, duck?s, quail?s, rabbit?s and turkey's meat. DNA from small amount of muscles (0.05 g) was extracted and a region of mitochondrial DNA (cytochrome-b gene) in chicken, duck, quail, rabbit and turkey was amplified by PCR. Fragment length of the PCR product was 371 bp in chicken, 374 bp in duck and rabbit and 377 bp in both quail and turkey. Six nucleotides different makes it difficult to differentiate among these five species-specific meat. For differentiation, three different restriction enzymes (DdeI, MspI

Abstract To further define the binding site for receptors for 1,25(OH)2D3 (VDR) in the bovine PTH gene and to study the interactions of transcription factors with VDR, Southwestern and gel shift assays were used. Data from the former indicated binding of VDR to DNA fragments spanning the regions −451 to −348 bp and −668 to −452 bp. Studies using gel shift assays confirmed binding to the −451 to −348 bp fragment and specificity was shown by using excess concentrations of unlabelled −451 to −348 bp fragment to compete for binding, whereas excess unlabelled −347 to +50 bp did not compete.

We have established an amplified fragment length polymorphism (AFLP) protocol for identifying anonymous polymorphic loci of the malarial parasite, Plasmodium falciparum. The method consists of the following steps (i) digestion and ligation in one reaction; (ii) selective fluorescence forward primers labelled; (iii) PCR products resolved in polyacrylamide gels using the ABIPRISMTM 377 XL DNA sequencer and, (iv) the use of GenescanTM software to size the fragments.

We hypothesize that peritoneal fluid tumor DNA (ptDNA) may be useful for PC detection and response monitoring. Currently, there are no established laboratory methods for ptDNA analysis.

With identification of this receptor a role of SDF-1 in directing chemotaxis of CXCR7+ hematopoietic cells as well as metastasis of CXCR7+ tumors become more complex.
