Recombinant, human pro-MMP-2 expressed in mouse cells. Useful for immunoblotting, substrate cleavage and assay zymography. The ~72 kDa purified proenzyme MMP-2 may be used as a positive control or standard for zymographic analysis, immunoblotting, or substrate cleavage assays. Requires activation prior to use. Matrix metalloproteinases are members of a unique family of proteolytic enzymes that have a zinc ion at their active sites and can degrade collagens, elastin and other components of the extracellular matrix (ECM). These enzymes are present in normal healthy individuals and have been shown to have an important role in processes such as wound healing, pregnancy, and bone resorption. However, overexpression and activation of MMPs have been linked with a range of pathological processes and disease states involved in the breakdown and remodeling of the ECM. Such diseases include tumor invasion and metastasis, rheumatoid arthritis, periodontal disease and vascular processes such as angiogenesis, intimal hyperplasia, atherosclerosis and aneurysms. Recently, MMPs have been linked to neurodegenerative diseases such as Alzheimer′s, and amyotrophic lateral sclerosis (ALS). Natural inhibitors of MMPs, tissue inhibitor of matrix metalloproteinases (TIMPs) exist and synthetic inhibitors have been developed which offer hope of new treatment options for these diseases.

Citric acid is a key metabolic intermediate. Citrate is the starting point of the tricarboxylic acid cycle. Its concentration also coordinates several other metabolic pathways. Citric acid can form complexes with various cations, particularly with iron and calcium. In animals, citric acid improves the utilization of nutritional calcium. Citric acid is produced commercially by fermentation of carbohydrates derived from corn starch and from beet molasses.
Citric Acid, Trisodium Salt, Dihydrate is used as a substrate for citrate lyase, a buffer component; an anticoagulant. For anticoagulation use it is typically used at a concentration of approximately 0.129 M (i.e. for 4.5 mL blood use 16.0 mg sodium citrate and 2.1 mg citric acid).
To make a sodium citrate buffer use equimolar concentrations (typically approximately 0.05 M concentration) of citric acid, free acid and sodium citrate. Add equal volumes of each solution and titrate to the desired pH.
