Cayman Chemical L-745 870hydrochlorIde 100mg
A dopamine D4 receptor antagonist (Ki = 0.43 nM); selective for dopamine D4 receptors over dopamine D2 and D3 receptors (Kis = 960 and 2,300 nM, respectively); selective for dopamine D4 receptors over α2A-, α2B-, and α2C-adrenergic receptors (IC50s = 0.00043, 0.16, 0.17, and 0.23 µM, respectively) and 5-HT2C and 5-HT1A receptors (IC50s = 0.2 and 2.9 µM, respectively); inhibits dopamine-induced inhibition of forskolin-induced cAMP production in HEK293 cells expressing human dopamine D4 receptors at 100 nM; inhibits mescaline-induced head twitches in mice at 3, 10, and 30 mg/kg
Cole-Parmer Oakton Conductivity and TDS Standard, 1413 µS; 500 mL
All Oakton Conductivity and TDS Standards are traceable to NIST standard reference materials. The solutions help you calibrate conductivity instruments to ensure accuracy with standard values given at 25C. Use when readings are expected to be around 1413 S/cm.
Cole-Parmer Oakton Traceable One-Shot™ Conductivity and TDS Standard, Assortment; 6 x 100 mL Vials
Oakton Traceable One-Shot™ conductivity and TDS standards include detailed KCl, NaCl, and 442 conversions, temperature corrections, and certified values referenced to 25C. Average accuracy at 25C is 0.25 microsiemens for 1, 5, 10 microsiemen (S) solutions, or 0.25% for all other solutions. The tested uncertainty is shown on the certificate, whichever is greater. Conductivity options range from 1 to 200,000 S/cm. Batch-tested solutions are lot certified; a few bottles from a single lot are analyzed
Cole-Parmer Myron L 30K QCP (NIST) conductivity calibration standard, 30,100 µS
Standards have NaCl and 442™ conversions included for ease of use. Conductivity values are accurate to within ±1% and are referenced to 25°C. Include a NIST-traceable calibration report supplied by the manufacturer for an additional fee. One 32-oz bottle.
YSI 3P LifeScience Conductivity Calibrator, 50,000 umhos/cm, 8/pk
NIST-traceable conductivity solutions to calibrate both field instruments and lab instruments and cells together for maximum accuracy.

Cayman Chemical L-745 870hydrochlorIde 5mg
A dopamine D4 receptor antagonist (Ki = 0.43 nM); selective for dopamine D4 receptors over dopamine D2 and D3 receptors (Kis = 960 and 2,300 nM, respectively); selective for dopamine D4 receptors over α2A-, α2B-, and α2C-adrenergic receptors (IC50s = 0.00043, 0.16, 0.17, and 0.23 µM, respectively) and 5-HT2C and 5-HT1A receptors (IC50s = 0.2 and 2.9 µM, respectively); inhibits dopamine-induced inhibition of forskolin-induced cAMP production in HEK293 cells expressing human dopamine D4 receptors at 100 nM; inhibits mescaline-induced head twitches in mice at 3, 10, and 30 mg/kg
Cole-Parmer Oakton Traceable One-Shot™ Conductivity and TDS Standard, 100,000 µS; 6 x 100 mL Vials
All Oakton Traceable conductivity standards are NIST-traceable reference materials Supplied with a calibration report from an ISO 17034 and ISO 17025 accredited laboratory These standard solutions let you calibrate conductivity instruments to ensure accuracy If unopened, shelf life is one year; once opened, shelf life will vary by solution value. Standards have detailed labels: KCl, NaCl, and 442 conversions, temperature corrections, and certified values referenced to 25C. Average accuracy at 25C is 0.25 microsiemens for 1, 5, 10 microsiemen (S) solutions, or 0.25% for all other solutions. The tested uncertainty is shown on the certificate, whichever is greater.
