QUANTOFIX® test strips meet all requirements of a modern rapid test. The colour of the reactive pad changes depending on the concentration of an analyte in the sample. The evaluation is usually carried out visually by comparison of the reaction colour with a multi-stage colour scale. QUANTOFIX® test strips are immediately ready-to-use. They do not require additional accessories. The test strips are intended for single use, maintenance or calibration are not required.

NUCLEIC dotMETRIC™ Kit provides a quick and accurate method for detecting and measuring nucleic acid concentration, including DNA, RNA and oligonucleotides. The system uses a combination of proprietary reagents and test strips and is an alternative to spectrophotometry as no equipment or cuvettes are necessary. NUCLEIC dotMETRIC™ uses as little as one microlitre of sample and provides permanent results within 2 to 3 minutes.

Bromelain is a glycoprotein which is a highly active thiol proteinase (non-specific cysteine protease), which splits glycine esters but not lysine esters; it is also a protein-digesting and milk-clotting enzyme. Substrates susceptible to bromelain include all of the common protein materials such as gelatin, casein, gluten, collagen, elastin, globulins an muscle fiber protein. It is a cysteine endopeptidase with broad specificity for cleavage of proteins. It may be from a stem or piece of fruit.

Bacterial PE LB™ kit has been developed for the extraction of biologically active soluble proteins, including recombinant proteins and inclusion bodies, from bacterial cells. Bacterial PE LB™ is a proprietary improvement on the lysozyme based lysis method, which allows extraction of soluble proteins and concurrent removal of nucleic acids (DNA and RNA) released during cell lysis. The Bacterial PE LB™ lysis system eliminates viscosity build-up, allowing effective clarification with lower centrifugal forces.

Supplier: SMEG

The laboratory glassware washer for washing and disinfecting of glassware and various laboratory material and used for washing up to 95 °C - antibacterical thermal disinfection.

Glycine is a non-essential amino acid. Acts as an inhibitory neurotransmitter, particularly in brain stem and medulla. Shown to block NMDA-stimulated dopamine release in fetal mesencephalic cell cultures. Also reported to increase NMDA-receptor mediated synaptic potential in cortical neurons. It does not have a chiral center, so only amino acid with no asymmetric carbon. Therefore, it does not have a D- or L- isomer designation. This material is synthetic. It is the smallest of the 20 natural amino acids.

Soluble in distilled water. Soluble in 0,1 M potassium phosphate buffer, pH 6,0 (monobasic potassium phosphate adjusted to pH 6,0 with 1,0 M potassium hydroxide) (10 mg/ml yields a clear, red-brown solution). Solutions of HRP can be kept refrigerated for up to a year while maintaining practically undiminished activity. Optimal pH is 6,0 to 6,5 (activity at pH 7,5 is 84% of the maximum). The enzyme is most stable in the pH range of 5,0 to 9,0 (Lit.).

Amphotericin B is a polyene antifungal antibiotic from Streptomyces. It has an affinity for sterols, primarily ergosterols, of fungal cell membranes. It forms channels in the membranes, causing small molecules to leak out which contributes to cell death.

Streptavidin Resin is designed for the single step small and large scale affinity purification of proteins and antibodies with a biotin tag. Biotin, a 244 Da vitamin (Vitamin H) molecule, exhibits an extraordinary binding affinity for avidin (Ka=10¹⁵ M⁻¹) and streptavidin (Ka=10¹⁵ M⁻¹). Biotin and (strept)avidin interaction is rapid and once the bond is established it can survive up to 3M guanidinehydrochloride and extremes of pH. Biotin-avidin bonds can only be reversed by denaturing the avidin protein molecule with 8M guanidine-hydrochloride at pH 1,5 or by autoclaving. The biotinylated molecules are efficiently probed with avidin or streptavidin conjugated to reporter molecules, such as peroxidases or phosphatases.
