Purified Human Serum IgA, Alpha Chain (>98%)
This secondary antibody is lyophilized from 0.01M phosphate buffered saline (PBS) pH 7.6 containing 0.25M NaCl, 15 mg/ml IgG free BSA and 0.05% sodium azide as a preservative.
This F(ab')2 secondary antibody was generated by optimal pepsin degestion of the antisera followed by antigen affinity chromatography to elimiate the presence of Fc fragment and whole molecules.
Storage and Handling
This lyophilized secondary antibody conjugate should be stored desiccated at 2-8°C. The reconstituted DyLight® 549 conjugate containing glycerol should be stored at -20°C in a manual defrost freezer.

It is recommended that working dilutions be prepared fresh daily. FC: IF: Secondary antibody concentrations reconstituted with glycerol will be diluted by 50%. Therefore, the working dilution may be one half of what is recommended.
Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change.
Goat F(ab')2 Anti-Human Serum IgA, Alpha Chain recognizes Human Serum IgA, Alpha Chain. This secondary antibody was purified using antigen affinity chromatography and has been adsorbed against serum proteins and immunoglobulins to minimize species cross-reactivity.
