1712722-0	1991	Application of silver staining to the rapid typing of the polymorphism of HLA-DQ alleles by enzymatic amplification and allele-specific restriction fragment length polymorphism.	Silver	15-21	major histocompatibility complex, class II, DQ alpha 1	Homo sapiens	74-77	
1712722-3	1991	Digestion of the PCR products by endonucleases, followed by their size-separation on polyacrylamide gels and visualization by silver staining, allowed us to define the HLA-DQ alleles of the genomic DNA.	Silver	126-132	major histocompatibility complex, class II, DQ alpha 1	Homo sapiens	168-171	
1712722-5	1991	Thus, silver staining in combination with PCR and allele-specific restriction fragment length polymorphism provides a simple, safe, and rapid method for accurate definition of HLA-DQ alleles at the nucleotide level in the clinical typing laboratory.	Silver	6-12	major histocompatibility complex, class II, DQ alpha 1	Homo sapiens	176-179
