MMP1,CLG,CLGN

Source

Human MMP-1, His Tag (MM1-H5222) is expressed from human 293 cells (HEK293). It contains AA Phe 20 - Asn 469 (Accession # NP_002412.1).

Predicted N-terminus: Phe 20

Molecular Characterization

MMP-1(Phe 20 - Asn 469)NP_002412.1
Poly-his

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 52.7 kDa. The protein migrates as 52-55 kDa under reducing (R) condition (SDS-PAGE).

Enzymatic Activity

Pre-activation is required for enzymatic assays. Please dilute Human MMP-1 to 100 µg/mL in TCNB buffer (50 mM Tris, 10 mM CaCl2, 150 mM NaCl, 0.05% Brij-35 (w/v), pH 7.5), and then add p-aminophenylmercuric acetate (APMA, Sigma, Cat. No. A-9563) to a final concentration of 1 mM. Please keep the enzyme with APMA for 1 hour at 37°C.
*100mM APMA stock solution should be prepared in DMSO. Please avoid adding high concentration APMA solution (>20mM) directly into the reaction as it tends to precipitate. A pre-dilution step is highly recommended.

Endotoxin

Less than 1.0 EU per μg by the LAL method.

 

Purity

>95% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in 20 mM MES, 150 mM NaCl, 10 mM CaCl2, 0.05% Brij-35, pH6.0. Normally trehalose is added as protectant before lyophilization.

Reconstitution

Please see Certificate of Analysis for specific instructions.

For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

Storage

For long term storage, the product should be stored at lyophilized state at -20°C or lower.

Please avoid repeated freeze-thaw cycles.

No activity loss is observed after storage at:

  1. 4-8°C for 12 months in lyophilized state;
  2. -70°C for 3 months under sterile conditions after reconstitution.
 

SDS-PAGE

Human MMP-1, His Tag (Cat. No. MM1-H5222) SDS-PAGE gel

Human MMP-1, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

 

Background

Proteins of the matrix metalloproteinase (MMP) family are involved in the breakdown of extracellular matrix in normal physiological processes, such as embryonic development, reproduction, and tissue remodeling, as well as in disease processes, such as arthritis and metastasis. Most MMPs are secreted as inactive proproteins which are activated when cleaved by extracellular proteinases. The enzyme encoded by this gene degrades type IV and V collagens. Studies in rhesus monkeys suggest that the enzyme is involved in IL-8-induced mobilization of hematopoietic progenitor cells from bone marrow, and murine studies suggest a role in tumor-associated tissue remodeling. Thrombospondins, intervertebral disc proteins, regulate the effective levels of matrix metalloproteinases (MMPs) 2 and 9, which are key effectors of ECM remodeling. Matrix metalloproteinase-1 (MMP-1) is also known as interstitial collagenase and fibroblast collagenase. MMP­1 is expressed by fibroblasts, keratinocytes, endothelial cells, monocytes and macrophages. MMP-1 breaks down the interstitial collagens, types I, II, and III. MMP­1 can degrade a broad range of substrates including types I, II, III, VII, VIII, and X collagens as well as casein, gelatin, myelin basic protein, L­Selectin, pro­TNF, IL­1β, IGF­BP3, IGF­BP5, pro MMP­2 and pro MMP­9.
