Tissue inhibitor of metalloproteinases 1 (TIMP1) and Tissue inhibitor of metalloproteinases 2 (TIMP 2) have similar properties, specifically in inhibiting enzymes of the matrix metalloproteinase family, and are thought to be of great importance in the maintenance of connective tissue integrity. TIMP1 forms a complex of 1:1 stoichiometry with activated interstitial collagenases, activated stromelysin, active form of 72kDa Type IV collagenase (also known as MMP2 or gelatinase A), and latent and active forms of 92kDa Type IV collagenase (also known as MMP0 or gelatinase B). TIMPs inhibit the proteolytic invasiveness of tumour cells and normal placental trophoblast cells. TIMP1 is produced in low (pg/mL) levels by most cell types. Treatment of cells with the phorbol ester TPA stimulates production of TIMP1 in some cell types, but the low protein levels produced often require concentration of cell culture media to visualize the bands by Western Blotting.

Ultra PFP Propyl columns are with a pentafluorophenyl propyl phase and has retention and selectivity of charged bases, electronegative compounds and amine-containing compounds.

Supplier: Restek

Ultra PFP columns are with a pentafluorophenyl phase and has unique selectivity for compounds containing organohalogens or other basic functional groups.

Supplier: Restek

PFP propyl columns have a pentafluorophenyl phase with a propyl spacer. It is highly retentive for basic analytes and phase for separating nucleosides, nucleotides, purines, pyrimidines, halogenated compounds, β-blockers and tricyclic antidepressants.

Supplier: Agilent

Rugged, high-resolution separations up to five times faster than traditional 5 µm methods.

Supplier: Thermo Fisher Scientific

Efficient separation of difficult mixtures containing closely related halogenated and polar compounds. The introduction of a fluorine group into the stationary phase causes significant changes in solute-stationary phase interaction and increases the selectivity and extra retention.

Supplier: Thermo Fisher Scientific

These columns offer alternative selectivity to C18, particularly for halogenated analytes. Based on Core Enhanced Technology, they provide fast, high resolution separations without the elevated back pressures required by sub-2 µm particles.

Supplier: Thermo Fisher Scientific

These reversed phase columns were developed in conjunction with the Vanquish™ UHPLC system to take advantage of the system's extended pressure capabilities and robustness. The result is a new level of separation, speed and throughput that solve analytical challenges of analysing complex matrices using liquid chromatography and LC-MS.
