Poly-L-Lysine Hydrobromide 30,000-70,000
A polycation, which binds to DNA, red cell membranes and any negatively, charged proteins. It is useful for promoting cell adhesion; for the preparation of polycationic beads, useful in immobilization techniques; immobilization of membranes; immobilization of plant protoplasts. In cell culture, immobilization by micro encapsulation with the alginate-poly-L-lysine microcapsule system.
We offer a prepared 0.1% aqueous solution, micro-filtered, which is ideal for cell culture growth.
Poly-L-Lysine Hydrobromide 70,000-150,000
Poly-L-lysine with a molecular weight of >70,000. This solution is useful in promoting cell adhesion to solid substrates. Used for nuclear antigen-coated red cells in hymolytic plaque assay.
We offer a prepared 0.1% aqueous solution which is micro-filtered and is used to increase tissue adhesion to the glass slide, which is needed for immunohistochemical and immunolabeling techniques, as well as lengthy staining procedures.
