Phyto Agar is a specially selected plant tissue culture agar with a high gel strength that is free of the extra salts of other agars which may adversely affect plant growth. Phyto Agar can be used in a minimal concentration of 5.0 g/L to obtain a solid gel.

Picloram is a synthetic auxin that is often used in the control of woody plants and broadleaf plants. Auxins typically act in concert with, or in opposition to, other plant hormones. For example, the ratio of auxin to cytokinin in certain plant tissues determines initiation of root versus shoot buds.

The plant hormones cytokinins (CKs) comprise a class of growth regulators involved in the stress response, senescence, photosynthesis, nutrient assimilation and mobilization, as well as modulation of a plant tissue’s ability to act as a sink or source of metabolites.

CKs are recognized by a subset of sensor histidine kinases (HKs) and the signal is transmitted to the nucleus via a multistep phosphorelay (MSP), thus activating the expression of target genes.

Pipemidic acid is a pyridopyrimidine antibiotic with similar properties to quinolone antibiotics. It is used to study damage and mutations in DNA as well as lymphocyte blastogenesis and interferon-gamma production. It can be used as a cell selection agent.

Piperacillin is an extended-spectrum β-lactam antibiotic resistant to many β-lactamases. It is derived from ampicillin and targets gram-negative and gram-positive bacteria. Additionally, piperacillin has been used in studies on optimization of antimicrobial therapy in patients with sepsis and to study piperacillin allergic reactions. It has also been used to study multidrug resistant organisms.

Piperonyl butoxide is an insecticide and synthetic inhibitor of cytochrome P450. It is synergistic to pyrethroids and rotenone.

PIPES is a buffering agent used in biochemistry and molecular biology that was selected and described by Good et al. It is a zwitterionic, piperazinic buffer that is useful for a pH range of 6.1 – 7.5. PIPES lacks the ability to form a significant complex with most metal ions and is recommended for use as a non-coordinating buffer in solutions with metal ions. PIPES has wide variety of applications and is commonly used in cell culture media, in protein crystallization, as a running buffer in gel electrophoresis, and as an eluent in isoelectric focusing and chromatography.

PIPES sesquisodium salt is a buffering agent used in biochemistry and molecular biology that was selected and described by Good et al. It is a zwitterionic, piperazinic buffer that is useful for a pH range of 6.1 – 7.5. PIPES lacks the ability to form a significant complex with most metal ions and is recommended for use as a non-coordinating buffer in solutions with metal ions. PIPES has wide variety of applications and is commonly used in cell culture media, in protein crystallization, as a running buffer in gel electrophoresis, and as an eluent in isoelectric focusing and chromatography. This buffer is capable of forming radicals and is therefore not suitable for redox reactions. It is suitable for use in the bicinchoninic acid (BCA) assay.

The pIRES-Luciferase-hRluc plasmid is designed to study gene expression, regulation, and co-expression of two reporter genes, firefly luciferase and Renilla luciferase, from a single mRNA transcript. This plasmid includes an Internal Ribosome Entry Site (IRES) that allows the simultaneous expression of both reporter genes, providing a powerful tool for studying transcriptional and translational regulation.

The pIRES-Luciferase-hRluc plasmid is a synthetic plasmid obtained from a third party and its sequence has been confirmed at GoldBio.

Duchefa Plant Agar is the preferred choice in Plant cell and Tissue culture as a general purpose agar and combines good quality with a favorable price. Agar is derived from red algae and is comprised of a mix of large polysaccharide agarose molecules and smaller, heterogeneous molecules called agaropectin. Plant agar can be used in a minimal concentration of 5.5 g/l to to obtain a solid gel.

Gold Biotechnology gravity flow empty columns are ideal for normal protein purification processes. Customers may buy bulk resins and then pack their own His-tag purification columns as an economic option.

These columns serve as tools for gravity purification using small quantities of resin. The package contains 50 plastic columns with their top and end caps.

The plastic columns are polypropylene with a total volume of either 12 mL or 35 mL and contain a polyethylene frit with a nominal pore size of 20 µm. They are specially designed for working with bead volumes of 0.5-2.0 mL (12 mL column) or 2-6 mL (35 mL column).
