About Sulfasalazine
Product name: Sulfasalazine
CAS NO: 599-79-1
Molecular formula: C18H14N4O5S
Molecular weight: 398.394 g/mol
Sulfasalazine is an anti-inflammatory medication that belongs to a class of drugs called sulfa drugs, a derivative of mesalazine (also called 5-aminosalicylic acid, or 5-ASA), used primarily as an anti-inflammatory agent in the treatment of inflammatory bowel disease as well as for rheumatoid arthritis and enthesitis related arthritis like juvenile spondyloarthropathies. It may be abbreviated SSZ.
Sulfasalazine is used in the treatment of inflammatory bowel disease, including ulcerative colitis and Crohn's disease. It is also indicated for use in rheumatoid arthritis and used in other types of inflammatory arthritis (e.g. psoriatic arthritis) where it has a beneficial affect. It is often well tolerated compared to other DMARDS.
Sulfasalazine has also been used successfully to treat cases of idiopathic urticaria that do not respond to antihistamines.

What is Baicllus
Bacillus is a genus of Gram-positive, rod-shaped bacteria and a member of the division Firmicutes. Bacillus species can be obligate aerobes or facultative anaerobes, and test positive for the enzyme catalase. Ubiquitous in nature, Bacillus includes both free-living and pathogenic species. Under stressful environmental conditions, the cells produce oval endospores that can stay dormant for extended periods. These characteristics originally defined the genus, but not all such species are closely related, and many have been moved to other genera.
Bacilli are an extremely diverse group of bacteria that include both the causative agent of anthrax (Bacillus anthracis) as well as several species that synthesize important antibiotics. In addition to medical uses, bacillus spores, due to their extreme tolerance to both heat and disinfectants, are used to test heat sterilization techniques and chemical disinfectants. Bacilli are also used in the detergent manufacturing industry for their ability to synthesize important enzymes.

What is Bifidobacterium-Bifidum
Product name: Bifidobacterium Bifidunm
Product description: Bifidobacterium bifidum is a probiotic, or a beneficial kind of bacteria. Bifidobacterium bifidum can be added to the diet through the use of supplements or the consumption of yogurt containing live culture.
Bifidobacterium Bifidum is a natural part of the human body. The inclusion of this species in the human body helps to build up the immune system, lower the cholesterol levels, lessens the chance of allergies, aid in digestion and helps to prevent the effects of tumors in colon cancer.
It has been used to help maintain and restore the normal balance of intestinal bacteria when the balance has been upset (e.g., with the use of antibiotics, certain stomach/intestinal conditions). Having a normal balance of intestinal bacteria helps to decrease episodes of diarrhea, protects against undesirable bacteria infecting the gut, and helps with proper food digestion and absorption of vitamins and minerals.Some dietary supplement products have been found to contain possibly harmful impurities/additives.

Host: Rabbit
Source: Human
Immunogen: Purified human granulocytic MPO.
Specificity: Recognizes human myeloperoxidase (MPO).
Applications: Suitable for use in Immunohistochemistry. Other applications not tested.
Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months.
Description: Myeloperoxidase is an important enzyme used by granulocytes during phagocytic lysis of engulfed foreign particles. In normal tissues and in a variety of myeloproliferative disorders myeloid cells of both neutrophilic and eosinophilic types, at all stages of maturation, exhibit strong cytoplasmic reactivity for MPO. Erythroid precursors, megakaryocytes, lymphoid cells, mast cells, and plasma cells are nonreactive. MPO is not observed in the neoplastic cells of a wide variety of epithelial tumors and sarcomas. MPO is useful in differentiating between myeloid and lymphoid leukemias.
Important Note: This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications without the expressed written authorization of United States Biological.

What is Lp-a ELISA Kit
Product name: Lp-a ELISA Kit
Advantages: Calibrated against a highly purified, fully validated
Storage: Store all components at 2-8 degree Celsius with the exception of the standard, which should be stored frozen.
Description: Lipoprotein(a) [Lp(a)] is an atherogenic lipoprotein particle formed by assembly of LDL particles and apo(a) bound to apoB-100 component of LDL . Apo(a) is the main constituent of Lp(a), has serine proteinase activity and is able of autoproteolysis . Apo(a) has 4548 amino acids, variable sizes from 200 to 700 kDa, multiple isoforms, and structural homology with plasminogen . It competes with plasminogen for its binding site, inhibiting tissue-type plasminogen activator 1 and leading to reduced fibrinolysis . The mean Lp(a) protein level ranged from 78 to 175 μg/ml depending on populations and the risk threshold is 300 μg/ml. High level of Lp(a) in blood is a risk factor for myocardial infarction (MI), coronary heart disease (CHD), cerebrovascular disease (CVD), atherosclerosis, thrombosis, and stroke .
Immunoassay for quantitative determination of human lipoprotein(a) in serum or plasma.
Dilute each serum or plasma specimen to be tested 1:400 with the Lp(a) specimen diluents provided. (Serum specimens with high Lp(a) levels should be diluted more than 1:400 for accurate Lp(a) determination.) A pre-dilution using PBS (phosphate buffer) may be done followed by a final dilution in specimen diluents to bring the serum or plasma final dilution to 1:400.

About Jo-1 ELISA Kit
Product name: Jo-1 ELISA Kit Category Name: Autoimmune Disease kits
ELISA method: Enzyme Linked Immunosorbent Assay
Detection Range: Qualitative elisa assay- Positive, Negative and Cut-off
Specificity: 99%
Sensitivity: 100%
Total Time: 60 min
Shelf Life: 12 months
Description: The Diagnostic Automation Jo-1 ELISA kit is intended for the detection and semi-quantization of antibodies to Jo-1 in human sera. The assay is to be used to detect antibodies in a single serum specimen. The results of the assay are to be used as an aid to the diagnosis of autoimmune disease. This is for in vitro diagnostic use.
Circulating antibodies to intra-cellular structures especially to nuclear antigens represent a characteristic feature of Jo-1 ELISA systemic autoimmune diseases. One of those antigens, Jo-1 (Aminoacyl-tRNA Synthetase), was first described in the serum of a myositis patient. A large number of patients with anti-synthetase syndrome suffer from interstitial lung disease, Raynaud’s Phenomenon, mechanic’s hands and arthritis. Anti-Jo-1 antibodies are strongly associated with isolated anti-Ro52 antibodies.
