Carboxyl groups, in the form of carboxy termini, aspartate residues or glutamate residues, can be targeted for biotin labeling using amine-derivatised biotin molecules. This reaction is mediated by a class of crosslinkers known as carbodiimides and results in the formation of an amide bond. The reaction with EDC, the most common carbodiimide crosslinker, is generally performed in an MES buffer at pH 4,5 to 5 and requires just minutes to complete.

Cross linkers are used for the identification of near-neighbour protein relationships and ligand-receptor interactions. Homobifunctional, amine-reactive NHS esters or imidates, and heterobifunctional, amine-reactive, photoactivatable phenyl azides are the most commonly used crosslinkers for these applications.

Amphotericin B is a polyene antifungal antibiotic from Streptomyces. It has an affinity for sterols, primarily ergosterols, of fungal cell membranes. It forms channels in the membranes, causing small molecules to leak out which contributes to cell death.

Trimethoprim is an antibacterial agent; a specific inhibitor of formylation; a dihydrofolate reductase inhibitor.
Trimethoprim is primarily used as an antibacterial agent. It has dihydrofolate reductase inhibitor activity with selectivity for the prokaryote enzyme. It is used to treat urinary tract infections, mild acute prostatitis, recurrent cystitis, asymptomatic bacteriuria during pregnancy and respiratory tract infections. The combination of trimethoprim and sulfamethoxazole interferes with the cellular metabolism of folic acid in the bacterial cell by blocking the biosynthesis of nucleotides. Trimethoprim binds to dihydrofolate reductase and inhibits the reduction of dihydrofolic acid (DHF) to tetrahydrofolic acid (THF). THF is an essential precursor in the thymidine synthesis pathway and interference with this pathway inhibits bacterial DNA synthesis.

DyLight™ PEGylated dyes display absorption spectra ranging from 550 nm to 783 nm. These reagents fluoresce over a broad pH range, are more intense than Alexa Fluor® or Cy® dyes in many applications and match the output wavelengths of common fluorescence instrumentation. Additionally, the water solubility of the DyLight™ reagents allows a high dye-to-protein ratio without precipitation during conjugation.

Trypan Blue is a blue acid dye with a strong affinity for cellulose containing substrates such as cotton; less affinity for proteinaceous materials. Trypan blue solution may be used in trypan blue based cytotoxicity and proliferation assays.
Trypan Blue is used as a vital dye which is especially important because it is taken up by the reticuloendothelial system.

Protein kinase C inhibitor (IC50 = 50-200 µM depending on assay conditions in MCF-7 cells or IC50 = 100 µM in rat brain). The PKC inhibition is also dependent on the phosopholipid concentration. Also inhibits both calmodulin-dependent and calmodulin-independent Ca2+-, Mg2+-ATPase. Tamoxifen is a selective estrogen response modifier (SERM), anti-angiogenetic factor. It is a prodrug that is metabolized to active metabolites 4-hydroxytamoxifen (4-OHT) and endoxifen by cytochrome P450 isoforms CYP2D6 and CYP3A4. In breast cancer, the gene repressor activity of tamoxifen against ERBB2 is dependent upon PAX2. Blocks estradiol-stimulated VEGF production in breast tumor cells.
Tamoxifen has been used to facilitate the recombination of ect2flox allele in mouse organs. It has also been used to study its effect on lipopolysaccharide (LPS)-induced microglial activation Tamoxifen is a Protein kinase C inhibitor. It induces apoptosis in human malignant glioma cell lines. Tamoxifen and its metabolite 4-hydroxytamoxifen are selective estrogen response modifiers (SERMs) that act as estrogen antagonists in mammary gland. Blocks estradiol-stimulated VEGF production in breast tumor cells.
