A fuzzy approach to image analysis in HLA typing using oligonucleotide microarrays

Typing of HLA Class I by Polymerase Chain Reaction-Sequence Specific Oligonucleotide Primer (PCR-SSOP) Technique in Iranian Cord Blood Donors

Background: HLA compatibility between transplant donor and recipient is one of the major determinants of transplant outcome. Objective: To determine HLA class I by PCR- Sequence-Specific Oligonucleotide Probe (PCR-SSOP) in cord blood donors. Methods: Genomic DNA of 142 cord blood samples registered at the Cord Blood Bank of Iran at Hematology, Oncology, and Bone Marrow Transplantation Researc...

Analysis of Oligonucleotide Microarray Images Using a Fuzzy Sets Approach in HLA Typing

High-Resolution HLA-A Typing in Normal Iranian Population

Background: Human leukocyte antigen (HLA) gene is a highly polymorphic region. HLA typing is required to match patients and donors for transplantation; therefore, development of HLA registries is necessary for finding HLA match donors. HLA system is highly informative, and numerous studies have been conducted on HLA allele distribution in different populations. Methods: In this study,...

An Efficient Covalent Coating on Glass Slides for Preparation of Optical Oligonucleotide Microarrays

Objective(s): Microarrays are potential analyzing tools for genomics and proteomics researches, which is in needed of suitable substrate for coating and also hybridization of biomolecules.   Materials and Methods: In this research, a thin film of oxidized agarose was prepared on the glass slides which previously coated with poly-L-lysine (PLL). Some of the aldehyde groups of the activated aga...

Mesenchymal stem cells as a reference cell for HLA-typing

Introduction: Recognition of human leukocyte antigens (HLA) is of importance for hematopoietic stem cell transplantation. Any HLA-mismatches between the donor and recipient can cause graft rejection or other complications. In HLA-typing experiments, usage of HLA-known reference cells accompany with HLA-unknown samples is obligatory. Some international centers represent these cells with high e...
