In spite of the fact that commercial bromelain supplements are available in the market, to date, none of them are produced and formulated from recombinant forms. They are extracted and purified (often partially) from the stem and fruit of pineapple (Ananas comosus). This makes the production of bromelain very difficult, less reliable, often contaminated and expensive. In this study, a recombina...

Radiolabeled monoclonal antibodies, have created new innovations in diagnosis, research and therapy of disease in last 2 decades. One of the serious limitation of applications of radiolabeled antibodies in vivo is relatively low target to background activity. Various strategies have been proposed to solve this problem including pre-targeting methods that was suggested in 1989. Regarding i...

Fast Protein Liquid Chromatography TM (FPLC), in which an anion-exchange column is used, provides rapid separation and reproducible profiling of the plasma proteins in urine and cerebrospinal fluid (CSF). Chromatographic separation of the proteins takes 1 h for urine specimens and 45 min for CSF. The elution sequence from the anion-exchange column is similar to the electrophoretic mobility. Ind...

Snake bite was known as one of the most important public health concerns world wild. Respiratory and cardiac problems and destruction of endothelium system occurs as a result of snake bite. Some proteins and peptides in snake venom have potential for drug discovery studies. According to the important role of cell adhesion and angiogenesis in cancer development, identification of new therapeutic...

Soybean (Glycine max (L.) Merr.) has emerged as one of the most economical and nutritious foods. Kunitz Soybean Trypsin Inhibitor (KSTI) and Bowman -Birk Inhibitor (BBI) are the two major trypsin inhibitors in soybeans. The ingested soybean trypsin inhibitors cause growth depression as demonstrated in different animal species and human. The main part of the present study was devoted to isolatio...

In this study, an easy, fast, sensitive and accurate technique has been described for extraction and quantitative analysis of fluoxetine and propafenone using off-line coupling of ionic liquid–based dispersive liquid–liquid micro-extraction with high performance liquid chromatography. The effective extraction variables including: the ionic liquid volume, the type and volume of dispersive solven...

in this project, eggshell membrane was used as a solid phase extraction sorbent for extraction of morphine followed by hplc analysis. at first, raw eggshell membrane was used and then, because of low adsorption of morphine on untreated eggshell membrane (

silymarin is a mixture of flavonolignans from the seeds of silybum marianum (l.) gaertner,containing silybinin, isosilybinin, silydianin, silychristin and the dihydroflavonol of taxifolin. flavonolignancomponents are largely responsible for the medical benefits attributed to silymarin. the aim of this researchwas to study the variations in composition and content of flavonolignans of silymarin ...

background and objectives:drimia maritima (l.) stearn also known as squill is a medicinally important plant that has been used for various ailments such as dropsy, respiratory disorders, jaundice and epilepsy from ancient times. proscillaridin a is identified as one of the most effective compounds in the plant with remarkable pharmacological features including efficacy against congestive heart ...

Murine T cell replacing factor (TRF) was purified from a cellfree supernatant of a T cell hybridoma (B151K12) that constitutively produces TRF. Two assay systems for TRF activity were employed: 1) induction of anti-DNP IgG PFC responses in cultures of splenic B cells from DNP-KLH-primed BALB/c mice, and 2) induction of IgM PFC in chronic B cell leukemic cells (BCL1). The purification scheme con...
