ACC Pyrochrome Kinetic Chromogenic Endotoxin Testing, 5 Pack (300 Test with Glucashield Buffer), part no. CG1500-5

Code: CG1500-5

  • Description
  • Other

Pyrochrome® sets the standard for quality and redefines the way chromogenic reagents should perform. 

Can achieve a maximum sensitivity of 0.001 EU/mL 

Option to use a sample to lysate volume ratio of 4:1 or 1:1 

Highly cost effective chromogenic reagent 

Use of polynomial regression for calculations
 

Pyrochrome is a versatile quantitative reagent that is used to perform kinetic or endpoint assays. It is a sensitive and flexible reagent that can be used for testing in compliance with the USP, EP and JP bacterial endotoxins test chapter. Pyrochrome is offered with either Pyrochrome Buffer or for endotoxin-specific testing, with Glucashield® Buffer. Pyrochrome can be used with the new Pyros Kinetix® Flex tube reader at a 1:1 and economical 4:1 ratio. 

Pyrochrome can be used for a wide variety of endotoxin tests, ranging from standard water testing to samples requiring high sensitivity, such as intrathecal products and those requiring high dilutions to overcome interference. The standard Pyrochrome test is read at 405–410 nm. 

It is also offered in a diazo kit for endpoint tests. (The diazo reagents shift the absorption spectrum making it especially useful for testing samples with color interference.) The test is read at 540–550 nm.

Product Sensitivity

The sensitivity for chromogenic assays is determined by the lowest standard concentration on the standard curve used for the assay. The maximum sensitivity of Pyrochrome is 0.001 EU/mL when run in Pyros Kinetix Flex tube reader or incubating microplate reader with Glucashield Buffer. 

Sample to Lysate Ratio

Reconstituted Pyrochome can be used at an economical ratio of 4:1 and a volume of 50 µL/well (60 test) in the Pyros Kinetix Flex tube reader. Pyrochrome LAL reagent can also be used at a ratio of 1:1 and a volume of 100 µL/well (30 tests/vial) or 50 µL/well (60 tests/vial) in a microplate reader. 

Test Performance

The Pyrochrome/sample mixture is incubated at 37±1°C and read in a microplate reader equipped with a 405–410 nm filter or 540–550 nm filter for diazo method. The time of incubation is dependent on the lowest standard concentration in the standard curve. Software is used to construct the standard curve and calculate the endotoxin concentrations.

Product Stability

Once reconstituted, Pyrochrome is stable for 8 hours when stored at 2–8ºC.

Product Reconstitution

Pyrochrome lysate is reconstituted with an optimized Pyrochome reconstitution buffer (C1500). Pyrochrome can also be reconstituted with Glucashield buffer, a (1→3)-ß-D-Glucan inhibiting buffer, to render the assay endotoxin specific (CG1500). 

Product Packaging

Pyrochrome is offered with a choice of reconstitution buffer and is recommended for use with the 10 ng/vial Control Standard Endotoxin (CSE,EC010). Certificates of Analysis, specific to the Pyrochrome and CSE lot, can be obtained from ACC or online at www.acciusa.com.
