Figure Lengend Snippet: Figure 4. Real-time PCR analyses of TSSK 1±4 expression. Relative levels of mRNA expression in human tissues were determined using multiple tissue cDNA (MTC) panels from BD Biosciences (USA) in real-time PCR reactions as described in Materials and methods. The point at which the PCR product is ®rst detected above a ®xed threshold, termed cycle threshold (Ct), was determined for each sample. Melting curve analysis con®rmed the ampli®cation of only the expected product. To determine the quantity of gene-speci®c transcripts present in each tissue relative to testis, their respective Ct values were ®rst normalized by subtracting the Ct value obtained from the GADPH control (e.g. ± DCt = Ct TSSK 3 ± Ct GADPH). The concentration of gene-speci®c mRNA in a given tissue relative to testis was then calculated by subtracting the normalized Ct values obtained with each tissue from that obtained with testis (e.g. ± DDCt = DCt of brain ± DCt of testis), and the relative concentration was determined (relative concentration = 2±DDCt).
Article Snippet: These primers were used in combination with adaptor primers from the adaptor-ligated Marathon ready testicular cDNA library (Clontech) to obtain the full length human TSSK 2 sequence using 5¢ and 3¢ rapid ampli®cation of cDNA end (RACE) as described by the manufacturer.
