Antibodies for human laminin isoforms

Targeting the Biolaminin human recombinant laminin isoforms, a panel of 17 monoclonal mouse antibodies has been developed to selectively recognize each specific subunit of the laminins, without any cross-reactivity to other subunits. The Laminin panel is developed by Atlas Antibodies using the same stringent conditions as for all PrecisA Monoclonals, guaranteeing defined specificity, multiplexing opportunities, secured continuity, and stable supply.

Laminin protein and gene expression in tissues

Study the expression of the laminin genes in different tissues, cell types and pathological states in The Human Protein Atlas.

The Human Protein Atlas is a program that aims to map all the human proteins in cells, tissues and organs using antibody-based imaging, mass spectrometry-based proteomics, transcriptomics and systems biology.
