Price range: RM685.00 through RM1,075.00Brand:
Plant Cell Technology
Gellan gum also known as Phytagel, Gelzan, Gelrite, or Applied gel is a water soluble anionic polysaccharide produced by fermentation of a carbohydrate by pseudomonas Elodea, purified, dried, and powdered.
Gellan gum is ideal for preparation of nutrient media for in plant tissue culture work and is a substitute for agar.Gels produced by gellan gum are clearer in comparison to agar however the gel is more rigid and brittle than agar gel. Gellan gum requires roughly half the amount of agar that is needed. Gellan gum melts at 80°C– 100°C and gels between 10°C-50°C.Gellan gum also known as Phytagel, Gelzan, Gelrite, or Applied gel is a water soluble anionic polysaccharide produced by fermentation of a carbohydrate by pseudomonas Elodea, purified, dried, and powdered.

Giolitti-Cantoni Broth, Oxoid Preparation:
Suspend 54.2g in one litre of distilled water and heat gently to dissolve. Dispense 19ml amounts into 20 x 200mm test tubes and sterilise by autoclaving at 121°C for 15 minutes. Cool rapidly then aseptically add to each tube 0.3ml of a sterile solution of Potassium tellurite 3.5% SR0030.
The medium requires the addition of a 3.5% solution of Potassium tellurite when there is a direct addition of 1g of the sample to 19mls of broth. This level of Potassium tellurite is necessary to suppress the high numbers of contaminating organisms that could be expected.
The use of a diluted solution of Potassium tellurite is applicable when a 1 in 10 dilution of the food sample is carried out. In such cases the SR0030 should first be diluted 1 in 10 with sterile distilled water.
The addition of 0.1% Tween 80 can be recommended in order to improve recovery of heat injured Staphylococcus aureus cells e.g. from milk powder. 1g of Tween 80 should be added to 1 litre of CM0523 prior to autoclaving.
Storage conditions and Shelf life
Store the dehydrated medium at 10-30°C and use before the expiry date on the label.
Store the prepared medium at 2-8°C.

General description
Glutathione (GSH) is the most important nonprotein thiol widely distributed in animal tissues, plants, and microorganisms. GSH is also a key determinant of redox signalling and protection against oxidative stress.
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
Application
HPLC: suitable
Gas Chromatography (GC): suitable
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
May be used at 5-10 mM to elute glutathione S-transferase (GST) from glutathione agarose.
Biochem/physiol Actions
Endogenous antioxidant that plays a major role in reducing reactive oxygen species formed during cellular metabolism and the respiratory burst. Glutathione-S-transferase catalyzes the formation of glutathione thioethers with xenobiotics, leukotrienes, and other molecules that have an electrophilic center. Glutathione also forms disulfide bonds with cysteine residues in proteins. Via these mechanisms, it can have the paradoxical effect of reducing the efficacy of anti-cancer agents.

Molar Mass: 92.09 g/mol
Synonyms: 1,2,3-Propanetriol, Glycerin
General description
Glycerol is odourless, colourless, viscous in nature, and exists as a sweet-tasting liquid. It can be derived naturally as well as from petrochemical feedstock. Glycerol has a wide variety of applications and is one of the most valuable and versatile chemical substances in nature. It can be used as an emollient, solvent, sweetening agent, in pharmaceutical formulations, cosmetics, foodstuffs and toiletries. It is very stable and can be easily stored under normal temperature; also it is non-irritating and has no adverse impact on the environment.
Application
Glycerol has been used as:
• A supplement during cell culture of Mycobacterium tuberculosis and Mycobacterium avium.
• A fuel during designing enzymatic biofuel cell.
• A liquid composite matrix with 4-HCCA and 3-aminoquinoline for analysis of neutral and acidic glycans.
• A matrix for fast atom bombardment MS.
• May be employed as liquid matrix for the quantification studies by MALDI (Matrix-assisted laser desorption/ionization mass spectrometry) analysis.
Glycerol is used both in sample preparation and gel formation for polyacrylamide gel electrophoresis. Glycerol (5-10%) increases the density of a sample so that the sample will layer at the bottom of a gel′s sample well. Glycerol is also used to aid in casting gradient gels and as a protein stabilizer and storage buffer component.

Description
Immunoglobulin G (IgG) is a multimeric immunoglobulin, built of two heavy chains γ and two light chains. Each complex has two antigen binding sites. It is one of the most abundant proteins in human serum with normal levels between 8-17 mg/ml in adult blood. IgG is important for our defense against microorganisms and the molecules are produced by B lymphocytes as a part of our adaptive immune response. The IgG molecule has two separate functions; to bind to the pathogen that elicited the response and to recruit other cells and molecules to destroy the antigen. Furthermore, this is the only isotype that can pass through the human placenta, thereby providing protection to the fetus in its first weeks of life before its own immune system has developed. The variability of the IgG pool is generated by somatic recombination and the number of specificities in an individual at a given time point is estimated to be 1011 variants.

General description
Gold nanoparticles, 20 nm, NHS ester functionalized, conjugation kit is a comprehensive kit that enables easy, one-step conjugation of your amine-containing ligands to 20 nm gold nanoparticles. The kit includes pre-made mixtures of lyophilized (freeze-dried) NHS-activated gold nanoparticles, along with all the necessary materials for three independent conjugation reactions. The kit components comprise:
- 3 vials of 20 nm NHS-Activated Gold Nanoparticles (lyophilized)
- Protein Resuspension Buffer – 1.5ml
- Reaction Buffer – 1.5ml
- Quencher Solution – 1.5ml
- Reaction protocol
The gold nanoparticles in this kit are supplied as a lyophilized (freeze-dried) mixture. The conjugation reaction is initiated by simply reconstituting the freeze-dried nanoparticles with the protein of interest, which attaches to the nanoparticle surface via lysine residues. The gold conjugation procedure has a quick hands-on time of around 10 minutes, and the conjugate is fully ready for use within 3 hr. Researchers only need to pipette the biomolecule into a vial containing the nanoparticles, quench the reaction, and perform product washing through microcentrifugation.
The provided protocol is optimized for highly efficient covalent conjugation, resulting in stable gold nanoparticle conjugates. Optional protocol steps involve additional materials, such as 10% aqueous BSA (126615) and Tris saline resuspension buffer (PPB002), which are sold separately.
Application
This gold conjugation kit streamlines the process of conjugating your proteins or biomolecules to 20 nm gold nanoparticles. Gold conjugation helps researchers to visualize and assay a specific protein or antibody of interest. Gold conjugates are useful in a wide range of applications like lateral flow testing, immunoblotting, immuno-electron microscopy, immunohistochemical staining, and other bio-assays.
Different sizes of gold nanoparticles perform better in specific applications. For lateral flow and flow cytometry, we recommend using gold nanoparticles with diameters between 20 nm and 100 nm. For immunoblotting or immuno-electron microscopy, the optimal range is 5 nm to 40 nm. For bioassays utilizing dynamic light scattering, gold nanoparticles with diameters ranging from 60 nm to 100 nm are suggested.
Features and Benefits
- The resulting covalent conjugates offer greater stability compared to those prepared using passive adsorption methods.
- Fast and convenient conjugation reaction with no need for pre-activation.
- A spacer between the gold nanoparticle surface and the conjugated ligand minimizes the impact on the tertiary protein structure. This reduces the likelihood of poor performing conjugates, a common issue encountered with conjugates prepared by passive adsorption.
- Gold surface coating is precisely engineered to minimize non-specific protein binding in biological assays.
