HPTLC plates with spherical particles, LiChrospher®

Supplier: Merck

HPTLC LiChrospher® plates are based on spherical-shaped silica 60 with a particle size of 7 µm, and narrow particle size distribution similar to the phases used in HPLC. LiChrospher® HPTLC plates possess a selectivity that is comparable to respective HPTLC plates, however, plate height and separation numbers are further improved resulting in shorter analysis times.

Dorsomorphin ≥98% (by TLC)

Supplier: ENZO LIFE SCIENCES

Cell-permeable pyrrazolopyrimidine derivative that inhibits AMP kinase (Ki=109nM in the absence of AMP) in an ATP-competitive manner. It displays no significant inhibition of ZAPK, SYK, PKCT, PKA and JAK3. Decreases food intake in mice and inhibits the effects of AICAR and metformin. It has been shown to inhibit BMP type I receptors ALK2, ALK3 and ALK6. Promotes cardiomyogenesis in mouse embryonic stem cells. Induces protective autophagy in cancer cell lines.

Midostaurin ≥98% (by TLC)

Supplier: ENZO LIFE SCIENCES

Inhibitor of a variety of serine/threonine and tyrosine kinases, like protein kinase C (PKC), cyclic AMP-dependent protein kinase (PKA), S6 kinase, Akt (protein kinase B; PKB), epidermal growth factor receptor (EGFR) tyrosine kinase activity and others including KDR, VEGFR, PDGFR, c-kit and other receptor tyrosine kinases. Potently inhibits FLT-3 kinase including mutant forms found in acute myeloid leukemia in vitro and in vivo. Apoptosis inducer. Showed broad antiproliferative activity against various tumor cell lines. Selectively inhibits T lymphocyte production of TNF-α. Upregulates endothelial nitric oxide synthase (eNOS; NOS III). Abrogates tumor angiogenesis in vivo.

Adenosine-3’,5’-cyclic Monophosphothioate, Rp-Isomer sodium salt ≥99% (by HPLC)

Supplier: ENZO LIFE SCIENCES

Competitive inhibitor of cyclic AMP-dependent protein kinase I and II.Metabolic stability towards mammalian cyclic nucleotide- responsive phosphodiesterases.
Discriminates between protein kinase A (antagonist) and some other cyclic AMP receptors, e.g. channels or CAP 3 (agonist).Membrane-permeant for several systems (for improved permeability more lipophilic analogues e.g. Rp-8-Br-cAMPS are recommended).

TLC and GLP plates, silica gel 60, unmodified layers, glass backed

Supplier: Merck

TLC plates, unmodified silica gel 60
Merck silica gel 60 has a unique polymeric binder that results in a uniform, hard surface that will not easily crack or blister. This smooth, extremely dense plate coating ensures narrow bands and maximum separation efficiency with the lowest background noise. Layer thickness 250 μm and particle size of 10 to 12 µm. Two inorganic fluorescent indicators for UV detection of colourless substances.

HPTLC and GLP plates, silica gel 60, unmodified layers, glass backed

Supplier: Merck

HPTLC plates, unmodified silica gel 60
This range of plates uses an optimised Merck silica gel 60 with a particle size of only 5 to 6 µm, which results in higher packing density and a smoother surface, therefore, reducing band diffusion. Less sample is required, 0,1 to 0,5 µl than for classic TLC.
