Description

GoldBio’s GV3101 Agrobacterium electrocompetent cells are a powerful tool for high efficiency transformation of plants. The GV3101 strain is optimized for cDNA and gDNA library construction, and possesses resistance to rifampicin, gentamicin, and tetracycline. The T-DNA region of the GV3101 Ti plasmid has been deleted, but restoration of the binary vector T-region can fully enable T-DNA binary system function.

The presence of the pSoup helper plasmid is required for the replication of pGreen, 62SK, and pGs2 series plasmids, and also helps with Agrobacterium-mediated transformation of dicotyledonous plants like Arabidopsis thaliana, tobacco, and potato, as well as monocotyledonous plants such as corn.

Description

GoldBio’s GV3101 electrocompetent Agrobacterium cells are a highly efficient tool for genetic transformation of dicotyledonous and monocotyledonous plant species, such as Arabidopsis thaliana, tobacco, potato, and corn. These cells carry the nopaline-type Ti plasmid pMP90 (pTiC58DT-DNA) that contains the vir genes required for the transfer and integration of T-DNA into the plant genome. Additionally, the cells are resistant to rifampicin, gentamicin, and tetracycline, which allows for selection of transformed cells.

The pSoup plasmid carried by the cells is required for the replication of pGreen, 62SK, and pGs2 series plasmids. The p19 protein is derived from tomato bush dwarf virus and improves the stability of heterologous gene transcripts by inhibiting RNA silencing of foreign genes. These combined properties make GV3101 electrocompetent Agrobacterium cells an ideal choice for cDNA or gDNA library construction and the generation of transgenic plants with desirable traits.

Description

GoldBio’s GV3101 Agrobacterium Electrocompetent Cells allow you to obtain high transformation efficiency in applications such as gDNA or cDNA library construction. Our GV3101 strain harbors the C58 chromosomal backbone containing rifampicin resistance and the Ti plasmid pMP90 (pTiC58DT-DNA) harboring the gentamicin resistance. A functional T-DNA binary system can be built using our GV3101 strains as the T-DNA region has been deleted from the Ti plasmid and instead has a binary vector containing the missing T-region. The binary system makes possible to transfer genetic material into a host plant’s genome. Our system is often used for Agrobacterium-mediated transformation in mono and dicotyledonous species such as Arabidopsis thaliana, tobacco, potato, soybeans and corn.

IFN-gamma, Equine

Catalog ID Size Pricing
1060-06-100 100 μg $ 365.00

Description

Interferon gamma is the only type II interferon and binds to the heterodimeric IFNGR that consists of two chains, IFNGR1 and IFNGR2. This interaction activates the JAK-STAT pathway. IFNG is produced primarily by T-lymphocytes and natural killer (NK) cells. It is critical for innate and adaptive immunity against viral and intracellular bacterial infections. This is due partly to its ability to inhibit viral replication directly, but also due to its immunostimulatory and immunomodulatory effects. IFNG induces the production of cytokines and upregulates the expression of class I and II MHC antigens, Fc receptors, and leukocyte adhesion molecules. It modulates macrophage effector functions, influences isotype switching, and potentiates the secretion of immunoglobulins by B cells. Additionally, IFNG augments TH1 cell expansion and may be required for TH1 cell differentiation.

Description

Interleukin-1 beta (IL1B) is a nonsecreted pro-inflammatory cytokine produced mainly by activated macrophages, as well as neutrophils, epithelial cells and endothelial cells. It possesses metabolic, physiological and hematopoietic activities, and plays one of the central roles in the regulation of immune responses. Both IL1A and IL1B bind to the same receptor and have similar but not identical biological properties.

IL1RN (IL-1RA), Equine

Catalog ID Size Pricing
1010-01C-5 5 μg $ 115.00

Description

IL1RN, initially called the IL1 inhibitor, is encoded by the IL1RN gene which is a member of the interleukin 1 cytokine family. IL1RN is secreted by various types of cells, including immune cells, epithelial cells and adipocytes. IL1RN functions to inhibit the activity of interleukin-1 by binding to the IL1R1 receptor, which prevents it from associating with the co-receptor IL1RAP. IL1RN is also used in the treatment of rheumatoid arthritis, an autoimmune disease in which IL1 plays a key role. The Equus caballus IL1RN is a single nonglycosylated polypeptide chain that has been shown to block the inflammatory responses induced by IL1 both in vitro and in vivo. The protein shows 26% amino acid homology to IL1β and 19% homology to IL1α.

1010-02A-100 100 μg $ 905.00
1010-02A-500 500 μg $ 1,849.00

Description

IL2 is a powerful immunoregulatory lymphokine produced by T-cells in response to antigenic or mitogenic stimulation. It is expressed by CD4+ and CD8+ T-cells, γδ T-cells, B-cells, dendritic cells, and eosinophils. The receptor for IL2 consists of three subunits that are present on the cell surface in varying preformed complexes. The 55 kDa IL2 Rα is specific for IL2 and binds with low affinity. The 75 kDa IL2 Rβ, which is also a component of the IL15 receptor, binds IL2 with intermediate affinity. The 64 kDa common gamma chain γc/IL2 Rγ, which is shared with the receptors for IL4, IL7, IL9, IL15 and IL21, does not interact independently with IL2. Upon ligand binding, signal transduction is performed by both IL2 Rβ and γc. It drives resting T-cells to proliferate and induces IL2 and IL2 Rα synthesis. It contributes to T-cell homeostasis by promoting the Fas-induced death of naive CD4+ T-cells but not activated CD4+ memory lymphocytes. IL2 plays a central role in the expansion and maintenance of regulatory T-cells, although it inhibits the development of Th17 polarized cells. This recombinant IL2 has been modified by substituting a serine for cysteine at position 141 of the original sequence.
