HLA Genotyping
HLA analysis is a complex process, requiring a large number of multiplex PCR reactions to obtain a patient’s full genotype. This means that DNA used in HLA analysis needs to be extremely pure and of sufficient quantity.

Step 1: DNA Purification
DNA extraction is a critical first step in the experimental workflow of DNA Sequencing and Fragment analysis. The overall quality, accuracy and length of the DNA sequence read can be significantly affected by characteristics of the sample itself, and the method chosen for nucleic acid extraction. Ideal methods will vary depending on the source or tissue type, how it was obtained from its source, and how the sample was handled or stored prior to extraction.
Step 2: PCR Amplification & Cleanup
Sonication or Enzymatic Digestion of Genomic DNA

Sequence Based Typing (SBT)
SeCore™ Kits are Invitrogen's latest line of high resolution HLA typing products based on sequenced based typing - the 'gold standard' of allele identification.For research use only. Not intended for any animal or human therapeutic or diagnostic use.
Step 3: Cycle Sequencing
Cycle sequencing is a simple method in which successive rounds of denaturation, annealing, and extension in a thermal cycler result in linear amplification of extension products. The products are then injected into a capillary. All current Applied Biosystems DNA sequencing kits use cycle sequencing protocols. For de novo sequencing we recommend Dye Terminator chemistry.

Step 4: Sequencing Reaction Cleanup
After the sequencing reaction, it is important to remove unincorporated dye terminators and salts that may compete for capillary electrophoretic injection. Unincorporated terminators can co-migrate with the sequencing template, resulting in basecalling errors, and excess salt translates to poor signal-to-noise ratios.

Step 5: Capillary Electrophoresis
After performing the post-sequencing reaction purification, samples are ready for analysis on an Applied Biosystems capillary electrophoresis-based genetic analyzer. During capillary electrophoresis, the products of the cycle sequencing reaction migrate through capillaries filled with polymer. The negatively charged DNA fragments are size separated as they move through the polymer in the capillaries toward the positive electrode.
