Complete Gene Expression Profiling Accessory Reagents

Page Type
Product Code
Definition
Complete gene expression profiling accessory reagent kits include all components necessary to perform transcript synthesis, fluorescent labeling, and detection and are intended to carry out all processing steps for separately cleared gene expression microarray assays which specify their use. They are designed and optimized for preparation of labeled complementary RNA (cRNA) target using total RNA isolated from specific clinical tissue specimens for hybridization to and measurement of fluorescently-labeled cRNA targets using a specified and cleared microarray instrumentation system. They may also include specified exogenous controls intended to monitor amplification and labeling processes.
Physical State
Should not include reagents to perform only part of gene expression assay processing steps (e.g., transcript synthesis but not labeling) or only individual components insufficient to carry out all processing steps or only RNA extraction and purification from specific clinical specimens. Should also not include reagents not intended for gene expression analysis, uncleared microarrays for gene expression, or cleared microarrays not specifying the reagent¿s use.
Technical Method
Complete accessory reagents for gene expression profiling are intended, designed, and optimized to carry out all assay processes. The reagents include all components, including enzyme mixes, labeling reagents, reaction buffers, and purification reagents for the preparation, amplification, and specific labeling of cRNA targets from purified total RNA, isolated from specific tissue specimens, and the fragmentation and hybridization of the labeled-cRNA to microarrays for cleared microarray expression assays which specify their use.

CFR § 862.2570 Instrumentation for clinical multiplex test systems

§ 862.2570 Instrumentation for clinical multiplex test systems.

(a) Identification. Instrumentation for clinical multiplex test systems is a device intended to measure and sort multiple signals generated by an assay from a clinical sample. This instrumentation is used with a specific assay to measure multiple similar analytes that establish a single indicator to aid in diagnosis. Such instrumentation may be compatible with more than one specific assay. The device includes a signal reader unit, and may also integrate reagent handling, hybridization, washing, dedicated instrument control, and other hardware components, as well as raw data storage mechanisms, data acquisition software, and software to process detected signals.

(b) Classification. Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 862.9. The special control is FDA's guidance document entitled “Class II Special Controls Guidance Document: Instrumentation for Clinical Multiplex Test Systems.” See § 862.1(d) for the availability of this guidance document.
