About Anti-HIF-2α (Hypoxia-inducible factor-2α)

  Product name:  Anti-HIF-2α (Hypoxia-inducible factor-2α)  Specification:  100ul/200ul/1ml
  Description:
  HIF is a heterodimer composed of an α-subunit and a -subunit. Although HIF- is constitutively expressed, its two dimerization partners, HIF-1α and -2α, are rapidly degraded in the presence of oxygen, via the ubiquitin-proteasome system.
  Hypoxia contributes significantly to the pathophysiology of major categories of human disease, including myocardial and cerebral ischemia, cancer, pulmonary hypertension, congenital heart disease and chronic obstructive pulmonary disease. HIF-2 alpha is predominantly expressed in highly vascularized tissues of adult humans and endothelial cells of the embryonic and adult mouse, whereas HIF-1alpha functions primarily in extravascular tissues. HIF-2 alpha is also a potent activator of the tie-2 gene, which is known to be selectively expressed in endothelial cells.

What is Warfarin metabolite 4

  Product name:  Warfarin metabolite 4  Molecular formulae:  C18H18O4
  Molecular weight:  296
  Chemical abstracts number:  119465-36-0
  Product discription:
  Warfarin metabolite 4 is a kind of secondary metabolites.
  The metabolism of the clinically utilized, anticoagulant warfarin [4-hydroxy-3-(3-oxo-1-phenylbutyl)-2H-1-benzopyran-2-one] by rat liver microsomes has been investigated. The structure of a new warfarin metabolite [4-hydroxy-3-(3-oxo-1-phenyl-1-butenyl)-2H-1-benzopyran-2-one] (dehydrowarfarin) has been determined by mass spectral comparison with the chemically synthesized compound. The formation of dehydrowarfarin is catalyzed by cytochrome P-450 and is unusual in that the final product is effectively dehydrogenated warfarin.

About Anti-Histone H1b(Histone H1.4)

Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form an octamer, around which approximately 146 bp of DNA is wrapped in repeating units, called nucleosomes. The linker histone, H1, interacts with linker DNA between nucleosomes and functions in the compaction of chromatin into higher order structures. This gene is found in the large histone gene cluster on chromosome 6, it is intronless and encodes a member of the histone H1 family. Transcripts from this gene lack polyA tails but instead contain a palindromic termination element.
The Specification of Anti-Histone H1b(Histone H1.4) include 100ul/200ul/1ml.

What is Anti-CXC-R3/CD183 (Chemokine receptorC-X-C chemokine receptor type 3)

Specification:100ul/200ul/1ml
Description:
Chemokine receptor CXCR3 is a Gαi protein-coupled receptor in the CXC chemokine receptor family. Other names for CXCR3 are G protein-coupled receptor 9 (GPR9) and CD183.
CXCR3 is able to regulate leukocyte trafficking. Binding of chemokines to CXCR3 induces various cellular responses, most notably integrin activation, cytoskeletal changes and chemotactic migration. CXCR3-ligand interaction attracts Th1 cells and promotes Th1 cell maturation.

Lactobacillus Acidophilus health effects

Adjust the intestinal flora balance, inhibit the proliferation of intestinal microbial poor.

Lactobacillus acidophilus has antagonistic effects on pathogenic microorganisms. Lactobacillus

acidophilus can secrete substances anti-biotin (acidophilus streptozotocin (acidolin), acidophilus

bacteria hormone (acidophilin), lactobacillus (1aetocidon)), on the antagonism of enteric pathogens.
Lactobacillus acidophilus and Bifidobacterium fermentation of a mixture of agents. Intake of milk

containing these two viable food is good for the digestive organs, especially for gastrointestinal

disorders in infants and some long-term oral antibiotics and patients with gastrointestinal dysfunction,

eating food containing both viable fermentation milk, you can quickly restore the normal intestinal

flora balance, inhibit the proliferation of spoilage bacteria, so a good nutritional health.

What is Anti-NGF-β

Product name:Anti-NGF-β
Specification:100ul/200ul/1ml
Description:
Nerve growth factor (NGF) is one of a family of neurotrophins that induce the survival and proliferation of neurons. In cell culture, NGF induces the formation of neurite projections and, in vivo, may stimulate the innervation of tissues. NGF plays a role in the repair, regeneration, and protection of neurons, and as such could serve as a therapeutic agent in neurodegenerative conditions such as Alzheimer's disease. NGF enhances survival, growth, neurotransmitter biosynthesis of sympathetic and sensory neurons; neurotrophic factor; cutaneous innervation; growth, differentiation and survival of B lymphocytes. It also has a possible role in allergy and tissue repair. NGF is found in the hypothalamus, pituitary, thyroid gland, testes, epididymis, vascular smooth muscle cells, fibroblasts, mast cells and eosinophils. NGF is upregulated by glutamate, vitamin D3, IL6, FGF basic, astrocyte specific IL1, TNF alpha, PDGF and TGF beta. It is downregulated by GABAergic neuronal activity, glucocorticoids and Schwann cell-specific TGF beta.

Leptospira ELISA Kit use instructions

1. In the storage and incubation process avoid exposure to strong light will reagents. All reagent
bottle caps must cover tightly to prevent evaporation and pollution, reagent avoid microbial pollution
by, because proteolytic enzymes interference will lead to wrong results.
2. Be careful drain reagent and strictly abide by the given incubation time and temperature. Please note
that the specimen from the standard /, enzyme combined or substrate, the first hole and the last hole
and the time interval between the sample if too big, will lead to different "advance incubation" time,
which obviously affect the accuracy of the measurement values and repeatability. And, washing not fully
will influence test results.
3. Kit save, part of the reagents store in 20 ℃-part of the reagents store in 2-8 ℃, specific to
label) on the shall prevail.
4. There will be a strong final twist salting-out, diluted in water heating can help to dissolve.

what is Tacrolimus

Tacrolimus is FK506, is extracted from a soil fungus macrolide antibiotic, has strong immunosuppressive
properties, is the strength of its drug cyclosporin A, 10-100 times, arise prevention of organ
transplant rejection is better than cyclosporine.
 Tacrolimus is only applied to the clinical history of more than ten years, the time is shorter.
Therefore, in some respects (Pharmacology and Toxicology) study is not comprehensive enough. The main
side effects of Tacrolimus nephrotoxicity, neurotoxicity, and circulatory system, digestive system,
respiratory system and cardiovascular system function. Tacrolimus can induce diabetes (odds of about 10%
to 30%), can cause severe ketoacidosis. Tacrolimus-related incidence of hypertension than CsA
significantly reduced. Tacrolimus and CsA with rapamycin compared with rapamycin is a calmodulin does
not interact with the new immunosuppressive agents, is considered to have no effect on blood pressure.
 Immunosuppressant macrolides (including FK506 and rapamycin, etc.) not only orally, but also for
external use, mainly for some skin diseases such as atopic dermatitis, psoriasis, lichen planus, contact
dermatitis and bald spots, etc. have a certain effect. In addition, "Arthritis and Rheumatism" magazine
(Arthritis Rheum 2003; 48:3328-3337) 12, says a report released last month, immunosuppressant tacrolimus
in 2 or 3mg / day dose of a single treatment of active rheumatoid arthritis (RA) appears safe and
effective, but usually larger doses greater improvements.
