Mouse Antibody Variable Region Gene Amplification Kit

Instruction manual

First Edition (Revised on April, 2016)

[PRODUCT INFORMATION]

This kit can be used for antibody variable region gene amplification in hybridoma, mouse peripheral blood mononuclear cells , mouse spleen cells and other tissues. In the early stage, extracted mRNA and oligo dt was used to reverse transcription into cDNA.. This kit improves component by expansionsystem, which guarantee the specificity of amplification and expand compatibility for all antibody genes. It can be used for amplification of mouse antibody gene in any hybridoma, amplification of all antibody genes in mice after immunization and construction of mouse antibody library.

4. The PCR products are used for 2% agarose electrophoresis. Take DNA band about 350bp as a template to expand and recycle by Sub-PCR. Antibody variable region gene are obtained after TA cloning and sequencing.

[IMPORTANT NOTES]

1. Avoid repeated freezing / thawing cycle, otherwise it will influence amplification efficiency.;

2. Prefer cDNA of fresh sample as template;

3. The preparation of reaction system should be on the ice.
