Agarose High Resolution is an intermediate melting agarose with approximately twice the resolution capability of routine agarose. It is a purified linear galactan hydrocolloid isolated from agar or agar-bearing marine algae. It is ideal for the resolution of small DNA fragments in the range 20 bp to 2000 bp.
Agarose high resolution is an intermediate melting and gelling point agarose which exhibits superior sieving characteristics. It is recommended for analytical gels of DNA fragments under 1000 bp and is ideal for small DNA fragments down to 20 bp can be separated on 6 % gels. It resolves fragments differing in size by only 2 bp. Its use avoids the need for PAGE Southern and Northern transfers can be achieved efficiently from them at concentrations up to 2%. DNA fragments can be purified with high efficiency from this agarose gels up to 4% by using either a purification kit or an electroelution system.

B-Phycoerythrin (B-PE), a fluorescent protein from phycobiliprotein family, is isolated from cyanobacteria and eukaryotic algae. Its primary absorption peak is at 545 nm with a secondary peak at 563 nm. B-PE consists of a, b and g subunits and is present as (ab)6g. B-PE and the closely related R-PE are the most intensely fluorescent phycobiliproteins having orange fluorescence. They are significantly brighter and more photostable than conventional organic fluorophores. B-PE labeled streptavidin, primary and secondary antibodies have been widely used in applications such as flow cytometry and multi-color immunofluorescent staining.

IPTG (isopropyl-β-thiogalactoside) is an analogue of allolactose that binds specifically to the repressor protein of the lac operon and induces expression of β-galactosidase in Escherichia coli.
IPTG is a commonly used reagent in cloning procedures that require induction of b-galactosidase activity and is used in conjunction with X-Gal in blue-white color selection of recombinant bacterial colonies.
The final concentration typically used in indicator plates is 0.2 mM.

SHC1 is a signaling adapter that couples activated growth factor receptors to signaling pathway. Isoform p46Shc and isoform p52Shc, once phosphorylated, couple activated receptor tyrosine kinases to Ras via the recruitment of the GRB2/SOS complex and are implicated in the cytoplasmic propagation of mitogenic signals. Isoform p46Shc and isoform p52Shc may thus function as initiators of the Ras signaling cascade in various non-neuronal systems. Isoform p66Shc does not mediate Ras activation, but is involved in signal transduction pathways that regulate the cellular response to oxidative stress and life span. Isoform p66Shc acts as a downstream target of the tumor suppressor p53 and is indispensable for the ability of stress-activated p53 to induce elevation of intracellular oxidants, cytochrome c release and apoptosis. The expression of isoform p66Shc has been correlated with life span.

Homeobox-containing genes are thought to have a role in controlling development. The human engrailed homologs 1 and 2 encode homeodomain-containing proteins and have been implicated in the control of pattern formation during development of the central nervous system.Homeobox-containing genes are thought to have a role in controlling development. In Drosophila, the 'engrailed' (en) gene plays an important role during development in segmentation, where it is required for the formation of posterior compartments. Different mutations in the mouse homologs, En1 and En2, produced different developmental defects that frequently are lethal. The human engrailed homologs 1 and 2 encode homeodomain-containing proteins and have been implicated in the control of pattern formation during development of the central nervous system. Publication Note: This RefSeq record includes a subset of the publications that are available for this gene. Please see the Entrez Gene record to access additional publications.

FXYD5 is a member of a family of small membrane proteins that share a 35-amino acid signature sequence domain, beginning with the sequence PFXYD and containing 7 invariant and 6 highly conserved amino acids. The approved human gene nomenclature for the family is FXYD-domain containing ion transport regulator. Mouse FXYD5 has been termed RIC (Related to Ion Channel). FXYD2, also known as the gamma subunit of the Na,K-ATPase, regulates the properties of that enzyme. FXYD1 (phospholemman), FXYD2 (gamma), FXYD3 (MAT-8), FXYD4 (CHIF), and FXYD5 (RIC) have been shown to induce channel activity in experimental expression systems. Transmembrane topology has been established for two family members (FXYD1 and FXYD2), with the N-terminus extracellular and the C-terminus on the cytoplasmic side of the membrane. This gene product, FXYD5, has not been characterized as a protein.This reference sequence was derived from AF161462.1 and ESTs; validated by multiple replicate ESTs and human genomic sequence.

PGE2 is one of the primary cyclooxygenase products of arachidonic acid and one of the most widely investigated prostaglandins. Its activity influences inflammation, fertility and parturition, gastric mucosal integrity, and immune modulation. The effects of PGE2 are transduced by at least four distinct receptors designated EP1, EP2, EP3, and EP4. Affinity constants (Kd) of PGE2 for these receptors range from 1-10 nM depending on the receptor subtype and tissue.
