<strong>BD</strong> Dispase<br />

Dispase is a bacillus-derived neutral metalloprotease that is<br />

recommended for recovering cells cultured on <strong>BD</strong> Matrigel <br />

Basement Membrane Matrix. <strong>BD</strong> Dispase will yield a single cell<br />

suspension far more gently and effectively than trypsin, collagenase<br />

or other proteolytic enzymes; it will not harm cells harvested for<br />

subcultivation or bioassays. In addition, <strong>BD</strong> Dispase may be used for<br />

tissue dissociation. <strong>BD</strong> Dispase cleaves fibronectin, collagen IV, and to<br />

a lesser extent collagen I, but it does not cleave collagen V or laminin.<br />

tIps<br />

Dispase is not only recommended<br />

to recover cells cultured on<br />

<strong>BD</strong> Matrigel Matrix, but is<br />

also useful in primary tissue<br />

dissociation .<br />

<strong>BD</strong> cell recovery solution<br />

<strong>BD</strong> Cell Recovery Solution allows for the recovery of cells cultured on<br />

<strong>BD</strong> Matrigel Basement Membrane Matrix for subsequent biochemical<br />

analyses. <strong>BD</strong> Cell Recovery Solution depolymerizes <strong>BD</strong> Matrigel Matrix<br />

gels without enzymatic digests and lengthy incubation periods at<br />

high temperatures. Cells are released without damage, thereby<br />

avoiding biochemical changes during incubation and digestion<br />

of extracellular portions of cell-surface receptors and adhesion<br />

molecules.<br />

Description Qty. cat. no.<br />

<strong>BD</strong> Matrigel Matrix after one hour at 2-8°C<br />

• Filtered (0.2 µm membrane) and tested for bacteria, fungi, and<br />

mycoplasma<br />

instructions for Use:<br />

<strong>BD</strong> Cell Recovery Solution is used full strength to recover cells from<br />

<strong>BD</strong> Matrigel Matrix. Complete protocol provided with product.<br />

storage and stability:<br />

Stable for at least three months at 2-8°C.
