Giemsa's stain, Technical Grade used as a blood stain, Sigma-Aldrich®
Supplier: SIGMA ALDRICH MICROSCOPY
Giemsa stain is a versatile differential stain that is widely used in hematology for blood and bone marrow specimens, clinical cytology specimens, bacteriology, histological biopsies, and tumor samples. Giemsa's staining solution is composed of methylene blue, azure, and eosin. It is a major histological stain due to its unique staining of chromatin, nuclear membranes, and cytoplasmic elements. The stain is frequently used in combination with other dye solutions: May-Grünwald’s solution for Pappenheim (MGG) and Wright-Giemsa.

Mouse Recombinant IL-17A (Animal free) (from E. coli)
Supplier: Shenandoah Biotechnology
Interleukin 17A (IL-17A), also known as CTLA-8, is a member of the IL-17 family of proteins. IL-17A is a proinflammatory cytokine that is secreted by activated CD4+ and CD8+ T lymphocytes. IL-17A acts through its receptor, IL-17R, to promote increased cytokine and chemokine secretion. In turn, the cytokines and chemokines mediate the immunoregulatory function of IL-17A by promoting the proliferation, maturation, and chemoattraction of neutrophils to inflammatory sites. Elevated levels of IL-17A are associated with rheumatoid arthritis, airway inflammation, allograft rejection, inflammatory bowel disease, psoriasis, cancer, and multiple sclerosis. Human, mouse, and rat IL-17A show activity on mouse cells.

Anti-FKBP25 Rabbit Polyclonal Antibody
Supplier: Bioss
FKBP25 is a member of the immunophilin protein family. The immunophilins are a highly conserved family of cis-trans peptidyl-prolyl isomerases that bind to and mediate the effects of immunosuppressive drugs, such as cyclosporin, FK506 and rapamycin. They inhibit T-cell proliferation by interrupting two specific cytoplasmic signal transmission pathways. FKBP25 is localized in the nucleus and is expressed in the brain, testis, ovary, and spleen. It may influence immunoregulation and cerebellum development, as well as protein folding and trafficking in neurons. FKBP25 associates with transcriptional repressor protein YY1 and histone deaceltylases, HDAC1 and HDAC2. FKBP25 may contain several casein kinase II phosphorylation sites, which are believed to be important for cell growth regulation.

Microcystis aeruginosa [D-Asp3]microcystin-LR
Supplier: ENZO LIFE SCIENCES
Microcystins are a group of cyclic heptapeptide hepatotoxins produced by a number of cyanobacterial genera. The most notable of which, and namesake, is the widespread genus Microcystis. Structurally, all microcystins consist of the generalized structure cyclo(-D-Ala1-X2-D-MeAsp3-Y4-Adda5-D-Glu6-Mdha7-). X and Y are variable L-amino acids, D-MeAsp is D-erythro-β-methylaspartic acid and Mdha is N-methyldehydroalanine. Adda is the cyanobacteria unique C20 β-amino acid 3-amino-9-methoxy-2,6,8-trimethyl-10-phenyl-deca-4,6-dienoic acid. Substitutions of the variable L-amino acids at positions 2 and 4 give rise to at least 21 known primary microcystin analogs and alterations in the other constituent amino acids result in more than 90 reported mycrocystins to date.

Analytical balances, Explorer® Auto-door
Supplier: OHAUS
A range of four-place balances incorporate touch screen, advanced weighing and touch-free proximity sensor technologies. The easy to use control unit can be mounted on the base, above the base on an optional column, on a wall, or remotely (up to a distance of 3 metres with an optional cable). The touch screen display, with universal icons and informative prompts, simplifies set-up functions and basic operation. The operator has the added choice to assign the use of any of the four proximity sensors for hands-free operation of print, zero, tare, calibrate, automatic draft shield door (left or right) or draft shield light. The hands-free operation enables the user to minimise/eliminate any possible contamination of the control keypad - particularly important for weighing of sensitive materials. The balances have multiple application modes for basic weighing to SQC applications together with short stabilisation times and optimised performance specifications.
