4-CPPU is a cytokinin class plant growth regulator that is used to promote plant cell division. This compound has been used to increase embryogenic potential by inducing somatic embryogenesis, assist in plant callus production and investigate effects on plant biomass growth. 4-CPPU has also been shown to stimulate organogenesis in some plant species, such as Rubus.

4-CPPU increases plant growth by inhibiting cytokine oxidase, a regulator of cytokinin activity. The exact type of inhibition has not yet been elucidated. Researchers have found 4-CPPU to function as a competitive inhibitor, while others have found it to behave as a noncompetitive inhibitor.

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

Abscisic Acid is a naturally occuring plant hormone involved in plant growth and stress response. It is produced partially via the mevalonic pathway in chloroplasts and other plastids. The production of ABA is accentuated by stress, including water loss or freezing temperatures. The activation of ABA can occur by one of two methods: 1) an ABA-glucose ester can form by attachment of glucose to ABA, or 2) the oxidation of ABA can occur to form phaseic acid and dihyhdrophaseic acid.

The transport of ABA can occur in both xylem and phloem tissues, and it can also be translocated through paranchyma cells. Some functions of ABA include stimulating the closure of stomata, Inhibition of shoot growth, induction of seeds to synthesize storage proteins, inhibition of the effect of gibberellins and the induction of gene transcription in response to wounding (especially for proteinase inhibitors).

Duchefa Gelrite^TM is a naturally derived gelling polymer that can be used in a variety of applications as a solidification agent instead of agar. Produced by microbial fermentation, Gelrite^TM is a highly purified, natural anionic polysaccharide with the variations commonly associated with agar. Gelrite^TM forms rigid, brittle, agar-like gels at approximately half the use level of agar in presence of soluble salt like Mg²⁺

and Ca²⁺. Gels prepared with Gelrite™ are remarkably clear in comparison to those formed with agar. Gelrite^TM contains no contaminating matters (e.g., phenolic compounds) as found in agar that are toxic to certain sensitive organisms.

Gibberellic Acid, also called Gibberellin A3, is a plant hormone in the family of gibberellins, a large class of naturally ocuring tetracyclic diterpene acids which promote cell growth and development. In small concentrations, GA3 is a potent, dihydroxylated gibberellin which commonly used in the triggering of seed germination, stem differentiation and plant maturation.GA3 is widely used to promote the production of larger grape bunches or the induction of other fruit without pollination or seed development.

Quick-Dissolve^TM Gibberellic Acid is a special formulation developed at GoldBio that dissolves more easily in water than standard gibberellic Acid. In our lab, KOH is not required to drive the Quick-Dissolve^TM Gibberellic Acid into solution.

IAA (Indole-3-Acetic Acid) is the abundant and well known plant hormone of the auxin class.IAA is predominantly produced in the apical bud of and young leaves of plants and is known to be an inducer of cell division and elongation.IAA, as well as most other auxins, are also known to 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.

Auxin concentration varies depending on the part of the plant and the various concentrations are strictly regulated by the plant. The regulation of the auxin concentrations creates a pattern-like system which helps determine plant growth and development. IAA is often used in horticulture to promote adventitious root growth and are used commercially to create root stem cuttings and to promote uniform fruit and flowering growth.

IBA (Indole-3-butyric acid) is a plant hormone belonging to the auxin family and assists in initiating root formation; the in vitro process is called micropropagation. Aside from accelerating root formation, it is used on various crops to stimulate flower development and the growth of fruits. This ultimately increases crop yields.

Historically, products that contained IBA were used to protect plants during transplantation by stimulating root growth and decreasing shock.
