Secretory IgA, Human Colostrum from MyBioSource.com

Yes, Secretory Immunoglobulin A is the primary immunoglobulin found on mucosal surfaces, making it particularly relevant for studies focused on mucosal immunity and protection. Its role in preventing pathogen adherence and invasion on mucosal surfaces is well-documented, which can be beneficial for research in this area.

The J chain is crucial for the formation of multimeric IgA and IgM, facilitating their transport across epithelial cells to mucosal surfaces. This Secretory IgA product targets the joining chain of these immunoglobulins, which is essential for maintaining the structural integrity and functionality of secretory antibodies in mucosal immunity.

Yes, this Secretory IgA is specifically reactive to human targets, making it suitable for applications involving human samples, particularly in studies examining human mucosal immunity or related pathologies.

The product has a purity level of over 95% as determined by SDS-PAGE analysis. High purity is important as it minimizes background noise in experimental assays, ensuring that the results are reliable and attributable to the specific interactions of the Secretory IgA with its targets.
