Methotrexate is a cell cycle arresting agent with varying effects. Methotrexate has been reported to arrest the cell cycle in late G1/S thus leading to the inhibition of the synthesis of DNA, RNA, thymidylates, and proteins. The main mechanism of action is reported to involve the inhibition of enzymes involved in purine metabolism which leads to the accumulation of adenosine or the suppression of intercellular adhesion molecule expression by T cells. Additionally, this compound has been observed to inhibit DHFR.
Methotrexate is used for chemotherapy either alone or in combination with other agents. It is effective for the treatment of a number of cancers including: breast, head and neck, leukemia, lymphoma, lung, osteosarcoma, bladder, and trophoblastic neoplasms. It is also used in treatment of autoimmune diseases, ectopic pregnancy, and for the induction of medical abortions. It is used to inhibit dihydrofolate reductase in DHFR-based protein expression systems. Also effective in treatment of pyrimethamine-resistant Plasmodium vivax malaria parasites.
Potent inhibitor of dihydrofolate reductase and agent for antitumor studies. Use to inhibit dihydrofolate reductase in DHFR-based protein expression systems. Also shows immunosuppressive effects in, e.g., rheumatoid arthritis.
Methotrexate is an allosteric inhibititor of dihydrofolate reductase (DHFR), the enzyme that catalyzes the conversion of dihydrofolate to tetrahydrofolate. Since tetrahydrolfolate is required for purine and pyrimidine synthesis, methotrexate treatment results in the inhibition of DNA and RNA synthesis.

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.

The complement system provides innate defense against microbial infection and is a "complement" to antibody mediated immunity. The complement system consists of thirty five interacting plasma and membrane associated proteins which contribute to host-defense and initiate and amplify inflammation, even in the preimmune state where specific antibodies and lymphocytes are not available. In addition to the complement components themselves, this system also contains several soluble factors that prevent spontaneous complement activation from occurring in solution, as well as, several regulatory membrane associated proteins that protect host cells from accidental complement attack. Cleavage of the C3 component by either the classical pathway or the alternative pathway releases C3a and C3b. C3a appears to be important in many inflammatory responses while the C3b fragment covalently binds to the cell or bacterial surface and plays a role in opsonisation. Binding of C3b to the C4b component of the C3 convertase, results in C5 convertase (C4b3b2a) formation
