DBCO-PEG5-acid is an analog of DBCO-Acid with PEG linker and a DBCO group. DBCO group is a highly reactive cycloalkyne which is commonly used for copper-free Click Chemistry reactions. The hydrophilic PEG chain allows for increased water solubility of compounds in aqueous media. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Introduction
Intended Use
Used for the selective isolation and culture of Listeria monocytogenes.
Principle and Interpretation
Columbia Blood Agar Base provide carbon and nitrogen sources, vitamins and growth factors，maintains balanced osmotic pressure; Listeria hydrolyzes aesculin and reacts with iron ions to form black 6,7-dihydroxycoumarin; lithium chloride and other antibiotics can inhibit Gram-negative bacteria and most Gram-positive bacteria; agar is the coagulant of the culture medium.

This Rapid Test is for the detection of specific Aspergillus Galactomannan Antigen in Serum or Bronchoalveolar Lavage (BAL).
This product is manufactured by GaDia Diagnostics in Switzerland and distributed in Germany exclusively by Milenia Biotec.
Method/Platform
Immunochromatographic Rapid Test
Range/Assay Sensivity
Test Principle
The principle of the test is colloidal gold immunochromatography. If the sample is positive, the antigens in the sample react with the red-colored nanoparticles and form a complex (Antigen – anti-Aspergillus monoclonal antibodies – gold nanoparticles), which was previously pre-dried on the conjugate pad. The mixture then moves upward on the membrane by capillary action. As the sample flows through the test membrane, the binding conjugate complexes migrate. The anti-Aspergillus antibodies present on the membrane (Test Line) capture the colored conjugate complex and a red line will appear.
The Kit integrates phenol/guanidine-based lysis and silica membrane purification of total RNA. MagZol Reagent, included in the kits, is a monophasic solution of phenol and guanidine thiocyanate, designed to facilitate lysis of samples and inhibit RNases. The high lysis efficiency of the reagent and the subsequent removal of contaminants by organic phase extraction enable extracting up to 200μg total purified RNA from less than 100mg animal, plant, fungal samples,bacteria, cells and other samples.

Main Functions
Isolation total RNA (include miRNA) from 100mg lipid tissue, tissue, cell, plant, body fluids using columns and MagZol reagent
Applications
RT-PCR, qRT-PCR, Northern hybridization, second generation sequencing
Tissue samples (10-100mg) are homogenized in MagZol Reagent. After addition of chloroform, the homogenate is separated into aqueous and organic phases by centrifugation. The upper, aqueous phase is extracted, and ethanol is added to provide appropriate binding conditions. The sample is then applied to the spin column, where the total RNA (up to 100µg) binds to the membrane and phenol and other contaminants are efficiently washed away. High-quality RNA is then eluted in 30-100µl of RNase-free water.
Advantages
Efficient DNA removal – one step RNA extraction can effectively remove genomic DNA
High quality – one step RNA extraction reagent combined with silica gel column can obtain the highest concentration
Fast – several samples can be extracted in 30 minutes
High applicability – samples including animals, plants, bacteria, cells, etc.
High output – enable to process large samples and the yield can be up to 200μg

Storage and Stability
MagZol Reagent should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect its performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions.
