MaxLight(TM)550 is a new Yellow-Green photostable dye conjugate comparable to Alexa Fluor(TM)546, 555, DyLight(TM)549 , Cy3(TM), TRITC and offers better labeling efficiency, brighter imaging and increased immunodetection. Absorbance (550nm), Emission (575nm), Extinction Coefficient 150,000. TIMP-1and TIMP-2 have similar properties, specifically in inhibiting enzymes of matrix metalloproteinase family, and are thought to be of great importance in the maintenance of connective tissue integrity. TIMP-1 forms a complex of 1:1 stoichiometry with activated interstitial collagenase, activated stromelysin, active form of 72kDa Type IV collagenase (also known as MMP-2 or gelatinase A), and latent and active forms of 92kDa Type IV collagenase (also known as MMP-9 or gelatinase B). TIMPs inhibit the proteolytic invasiveness of tumor cells and normal placental trophoblast cells. Applications: Suitable for use in FLISA, Immunohistochemistry and Western Blot. Other applications not tested. Recommended Dilution: Immunohistochemistry: Frozen sections or acetone-fixed tissues. Formalin-fixed, paraffin-embedded sections are usually not reactive. PLP fixation is suggested as an alternative for paraffin-embedded sectons. Western Blot: 1:1,000. Identifies a band of approximately 30KDa. Note TIMP-1 is found in very low concentrations in most cells and tissues. Positive control is HT1080 cells treated with PMA or recombinant TIMP-1 protein. Optimal dilutions to be determined by the researcher. Storage and Stability: Store product at 4C in the dark. DO NOT FREEZE! Stable at 4C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: MaxLight(TM)550 conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Note: Applications are based on unconjugated antibody.
