Our lab is concerned with studying the transcriptome and signaling changes that occur during transitional B-cell development. This is a major checkpoint in peripheral tolerance where autoreactive B-cell clones are purged. This particular study examined the kappa to lambda light chain ratio in splenocytes.

Summary

The Good

Lambda light chain biotin works great.

The Bad

Each SAV conjugate will require separate optimization

The Bottom Line

This antibody provides great separation over many logs and can be used with many SAV fluorochrome conjugates
