Ammonium sulfate precipitaion problem - posted in Molecular Biology: Hi, I cannot fractionate transgene protein from plant protein by ammonium sulfate precipitation. The total protein is extracted from leave by TCA precipitation. In order to identify the protein of interest, the western analysis is performed. I can see the expected protein ban but it is hard to see. I cannot increase the amount of the protein in the SDS PAGE because the gel is overloaded. So I think ammonium sulfate can he...

Furhter to the sensible sounding advice of using a simple Ammonium Sulphate precipiation in conjunction with a nickel column His.Tag purification, can anybody give me advice on how to set yourself up for such a step. Whats the easiest and most systematic way of determining what percentages of Ammonium Sulphate are needed for a particular protein; come to think of it, how exactly do you do the precipitation? Is it best before or after the nickel column?

Hi Guys, I am expressing the recombinant protein 6xHis tagged at C terminal secreting in YP-Galactose media by K lactis. My problem is whenever i try to purify by using Ni-NTA column, it turns the column white as if supernatant is chelating Ni from the column. I tried to condition supernatant by adjusting pH 8.0 and Salt upto 1M with no success. Please suggest me what should i do. Ammonium sulphate precipitation result in inactivation of protein. i cant do dialysis economically to huge culture volume. so these will not be a good option for conditioning media. Thanks ...

LONDON - As one of the first and most widely used nitrogen fertilizers, ammonium sulfate is used mainly to supply various nutritional chemicals to growing plants. Proper usage of ammonium sulfate fertilizer helps to maintain healthy nitrogen levels and pH balance in soils. However, when used in excess it could cause a number of undesirable plant conditions.. In the years to come, the global market for ammonium sulfate fertilizer is set to keep on gaining traction, spurred by soaring demand for fertilizers on the back of constantly rising population along with decreasing arable lands. Moreover, shift in trend towards rising crop yield by enhancing nutrient contents in soil is also predicted to give a boost to the ammonium sulfate market growth.. Meantime, severe regulatory guidelines associated with the adoption of ammonium sulfate in countries like Germany, France, the UK and the USA are likely to significantly restrain the market growth in the offing.. Regionally, APAC dominates the worlds ...

0070] Phenyl Sepharose® HP hydrophobic interaction resin (GE Healthcare) and a Chromaflow® Acrylic chromatography column (GE Healthcare) were utilized for this process step. The phenyl column was 60 cm in diameter with a target height of 15±1 cm (bed volume 42.4 L). The loading limit for the column was 40 grams of sample per liter of Phenyl Sepharose® HP resin. The step was performed at 17±2° C., and at a flow rate of 75 cm/hr. The load material was warmed, when required, to 17±2° C. prior to the start of the first cycle. The column was pre-washed with water and equilibrated with 1.0 M ammonium sulfate and 18 mM sodium phosphate, pH 7.0. Following equilibration, the column was loaded with the diluted phenyl load. After loading, the column was washed to baseline absorbance (A280) with 1.1 M ammonium sulfate and 20 mM sodium phosphate, pH 7.0, followed by 0.95 M ammonium sulfate and 17 mM sodium phosphate, pH 7.0, respectively. The product was eluted from the column at a reduced flow rate ...

Ammonium Sulphate (AS) is an inorganic salt which is commonly use as soil fertilizer for alkaline soils to lower pH balance of soil, while contributing essential nitrogen for plant growth. This material is a by-product of the facility ammonia scrubbers, which remove levels of airborne ammonia from the compost tunnel air exhaust stream. This ammonium sulphate has fertilizer properties and Orgaworld London has registered this product with the Canadian Food Inspection Agency (CFIA) as a fertilizer. In 2016 the London facility produced 1,986 tonnes of ammonium sulphate.. ...

The sulfate radical adds to the alkene to give a sulfate ester radical. It is also used along with tetramethylethylenediamine to catalyze the polymerization of acrylamide in making a polyacrylamide gel, hence being important for SDS-PAGE and western blot. Illustrative of its powerful oxidizing properties, it is used to etch copper on printed circuit boards as an alternative to ferric chloride solution.[5] This property was discovered many years ago. In 1908, John William Turrentine used a dilute ammonium persulfate solution to etch copper. Turrentine weighed copper spirals before placing the copper spirals into the ammonium persulfate solution for an hour. After an hour, the spirals were weighed again and the amount of copper dissolved by ammonium persulfate was recorded. This experiment was extended to other metals such as nickel, cadmium, and iron, all of which yielded similar results.[6] The oxidation equation is thus: ​1⁄2 S ...
In order to detect the expression of the target genes in leukocytes and to optimize the reaction conditions for real-time quantitative PCR, reverse transcriptase PCR (RT-PCR) was performed using specific primer sets (Table 1). cDNA synthesis was performed using the iScriptTM cDNA Synthesis kit (Bio-Rad). The PCR mixture contained 1× PCR buffer (16.6 mM ammonium sulfate, 67 mM Tris, pH 8.8, 6.7 mM MgCl2, 10 mM 2-mercaptoethanol), dNTPs (each at 1.25 mM), primer pairs (100 pM each per reaction), and 10 ng of cDNA template in a final volume of 50 µl. Reactions were hot-started at 95 °C for 5 min before adding 1.5 units of Taq polymerase (Red-Hot®, Thermo Fisher Scientific, ABgene product line) at the annealing temperature of 56 °C, followed by polymerization at 72 °C for 1 min. Amplification was carried out in DNA Thermal Cycler TC480 (Perkin Elmer, Waltham, MA) for 45 cycles (denaturation for 45 s at 95 °C, annealing for 45 s at 56 °C, and polymerization at 72 °C for 30 s), followed by a ...
Maintain unopened vial at -70°C for up to 6 months. Avoid repeated freeze/thaw cycles. PREPARATION AND USE: To reconstitute the antibody, centrifuge the antibody vial at moderate speed (5,000 rpm) for 5 minutes to pellet the precipitated antibody product. Carefully remove the ammonium sulfate/PBS buffer solution and discard. It is not necessary to remove all of the ammonium sulfate/PBS solution: 10 µL of residual ammonium sulfate solution will not affect the resuspension of the antibody. Do not let the protein pellet dry, as severe loss of antibody reactivity can occur. Resuspend the antibody pellet in a suitable biological buffer such as PBS or TBS (pH 7.3-7.5) to a final concentration of 1.0 mg/mL. For example, to achieve a 1.0 mg/mL concentration with 50 µg of precipitated antibody, the amount of buffer needed would be 50 µL. Carefully add the liquid buffer to the pellet. DO NOT VORTEX. Mix by gentle stirring with a wide pipet tip or gentle finger-tapping. Let the precipitated antibody ...
