[A method for Rhesus box test].

To study the method for Rhesus box test and its significance, the sequence specific primers of upstream, downstream and hybrid Rhesus boxes were designed according to RhD gene sequence; the upstream, downstream and hybrid Rhesus boxes were determined by PCP-SSP and mismatched PCR. The results showed that this method was confirmed by DNA Standard test. It was shown that in unrelative RhD positive individuals RHD(+)/RHD(-), RHD(+)/RHD(+) genotype accounted for 9.00%, 91.00% respectively, and in RhD negative individuals RHD(+)/RHD(-), RHD(+)/RHD(+), RHD(-)/RHD(-) genotype were 26.14%, 3.92%, 69.94% respectively. It is concluded that the method of Rhesus box test was confirmed to be reliable and can be used for the identification of RhD haplotype gene structure, as well as for study on inheritance, clinical transfusion and neonatal hemolytic diseases.

[Method of detection of soluble HLA-I and soluble HLA-I level alteration in storage blood].

Aim of this study was to develop the detection method of soluble human leukocyte antigens I (sHLA-I) and to explore sHLA-I level alteration in storage blood and its significance. sHLA-I level in sera of 60 Guangdong normal individuals and sHLA-I concentration in blood components from 20 donors quantitatively were detected by sandwich ELISA. The results showed that sensitivity of this assay was 2.84 ng/ml. Coefficients of variation were 5.80% within assays and 9.00% between assays respectively. The recovery rate was >/= 98.57%. The sHLA-I level of normal individuals in Guangdong was (699.54 +/- 360.10) ng/ml. sHLA-I in red blood cells stored for 28 days and in random-donor platelets were significantly higher than that in other blood components and their amount was proportionate to the number of residual donor leukocytes and to the length of storage. In conclusion, sandwich ELISA assay for detection of sHLA-I is a sensitive, specific and stable technique. Blood components with different concentration of sHLA-I may be chosen for clinical transfusion.
