Four breeds of chickens (Gallus gallus), White Leghorn, Yangshan, Taihe Silkies and White Recessive Rocks ,with different egg production were applied to screen potential haplotype related to reproduction trait in part region of prolactin gene based on DNA pooling and sequencing.

DNA was extracted from these seven breeds and DNA pools were constructed respectively.

Forty-eight DNA pools were prepared using standardized DNA extracted from 152 Ganoderma isolates (128 Chinese isolates and 24 non-Chinese isolates) delineated on the basis of ERIC-PCR data.

To investigate the relationship between the single nucleotide polymorphism (SNPs) of the bcr and abl gene and chronic myelogeous leukemia (CML), the 9 sequence-tagged sites (STS) in bcr and abl gene were screened by DNA pooling and denaturing high performance liquid chromatography (dHPLC), and the results were varified by sequencing.

Four breeds of chickens (White Leghorn,Yangshan,Taihe Silkies,White Recessive Rocks) with different egg production were applied to screen potential single nucleotide polymorphisms (SNPs) related to reproduction trait in distal part region of prolactin gene based on DNA pooling and sequencing.

Based on the similarity index of pooled DNA.

Methods A total of 30 microsatellite markers on chromosome 2 spaced at about 10 cM were selected and two separated DNA pooling samples consisting of 450 essential hypertension cases and 450 normal controls were genotyped respectively.

The interaction of three chosen non-steroidal anti-inflammatory drugs (NSAID), indomethacin, sulindac and tolmetin with calf thymus DNA has been investigated by fluorescence with the use of fluores- cence probes, ethidium bromide (EB) and neutral red (NR).

The interaction of the complex with calf thymus DNA have been investigated by electronic and emission spectra, and the results shown the complex bind to DNA with high affinity.
