      Overview

      This product has been discontinued.



      Native MMP-9-lipocalin complex from stimulated human neutrophils. Disulfide-bridged complex of MMP-9 and a 25 kDa protein that belongs to the lipocalin family and displays homology with the α2-macroglobulin-related protein from rats. Lipocalin modulates MMP-9 activity by protecting it from degradation. Enzyme should be activated just prior to use.

      M.W. 130,000 (non-reducing SDS-PAGE). Note 1 mU = 1 milliunit.

      Recommended reaction conditions

      Organomercurial Activation Protocol This protocol is provided only as a general guide. Researchers should standardize this assay for their own specific needs and should consult published literature. The following protocol is from Stricklin, et al., which describes the use of p-aminophenylmercuric acetate (APMA) to activate pro-MMP. This protocol is also adaptable to other types of organomercurals, such as p-(hydroxymercuric) benzoate (PHMB), phenylmercuric chloride (PMC), or mersalyl. 1. Prepare a 10-50 mM stock solution of APMA (or other organomercurial compound) in 0.1 M NaOH just prior to use. Although not absolutely necessary, the stock solution may be adjusted to pH 11 with 5 N HCl (see Marcy, A.I., et al.). 2. To initiate the activation mix the proenzyme solution with the APMA solution at a 10:1 volume ratio (MMP:APMA). If a higher concentration of APMA is desired, increase the concentration of the stock solution. Do not exceed the 10:1 ratio, as this could result in significant changes in pH. 3. Incubate the mixture at 37°C for 2-3 h. It is recommended that an analytical run be conducted first to determine the optimal incubation time. For example, a small-scale experiment with a fixed concentration of pro-MMP and organomercurial would be incubated as described above. Remove aliquots of the sample at various time points during the incubation. Stop the reaction by the addition of SDS-PAGE sample buffer (e.g., 10 µl 2X sample buffer to 10 µl aliquot) and heat the samples to 95°C. The progress of activation can be monitored qualitatively by analyzing the aliquots on a 12% SDS-PAGE gel. 4. The activated MMP can be used without removing the APMA from the mixture. Please refer to Marcy, A.I., et al. for removal of organomercurials by gel filtration.
