The osmolality of standard cell growth media for mammalian cells is 300mOsm/kg, an optimal value for most cell lines.

Following are frequently asked questions regarding the use of osmolality in the pharmaceutical, biotechnology, and sports medicine applications.

In scientific terms, osmolality is a measure of the number of particles in a solution. For example, water has a very low osmolality (close to zero) where cranberry juice cocktail has a very high osmolality because there are a lot of sugar molecules dissolved in it. The osmolality of Gatorade is close to that of our blood, a factor that helps assure rapid absorption. If beverage osmolality becomes too high (e.g. soft drinks and fruit juices), the rate of fluid absorption is slowed.

Osmolality is a measure of the number of particles in a solution and can affect the functionality of fluid replacement drink. The osmolality of Accelerade ranges from approximately 345 to 365 mOsm/kg. Data in the literature suggests that beverages in the range of 0 to 400 osmolality do not affect intestinal absorption or fluid homeostasis during moderately intense exercise.

No, the strains can be grown in the usual media like YPD, BMGY, BMMY, etc. The genomic integration of the plasmids is sufficiently stable, so no antibiotics need to be added.

Answer: Most established vertebrate lines will tolerate a rather large variation in osmotic pressure. The useful range of osmolality of cell culture media for vertebrate lines is between 260 to 320 mOSM/kg. Invertebrate lines vary greatly in their sensitivity to osmotic pressure. For example, the snail embryo ATCC CRL-1494 requires medium of about 155 mOSM/kg, while some insect media prefer 360 to 375 mOSM/kg.

Some children experience slow growth and stature ("failure to thrive"). In some cases, depending on the circumstances, supplements are required and growth hormones used when children consistently score below the 5th percentile of standard growth and development charts.

Are you getting paid or compensated in any way by any of the companies or web sites you link to? [ Updated March 01, 2005 ] Oh yeah, well how do you explain this picture? Obviously that bruise is from steroid use.[ Updated June 23, 2003 ] Why do you look so tense in your daily pictures? Why don't you smile in them? Why are your arms "puffed" out?

You will get only one inflorescence per growth; you need to mature another growth to get another inflorescence. There have been rare recorded instances of some plants pushing up 2 inflorescences from the same growth. The exception to this rule is plants from section Cochlopetalum, which will give you flowers sequentially on the same inflorescence for many months. Paphs can be frustratingly or tantalizingly (depending on your point of view) slow to push that bud up and open it. Paph.

It is not recommend to freeze growth media. The freezing of high nutrient medium will lead to irreversible precipitation of medium components. Go to top

After adding all the supplements to the basal medium, the medium becomes a complete growth medium. If the complete growth medium is stored at 4°C and the duration for which the medium is kept at room temperature or 37°C is as short as possible for each use, the shelf-life time for the complete growth medium is 6 weeks. Go to top ScienCell's normal human cells have been cultured and tested in our complete growth medium and have adapted to this formula.

No. The optimal protocol, as provided with the FLIPR Calcium Assay Kit, assumes no removal of growth media from the cells. The FLIPR Calcium Assay Kit was developed and optimized to allow the direct addition of the reconstituted reagents to the cell wells, so obtaining a 1:1 dilution of reagent in growth medium. With the FLIPR Calcium Assay Kit, plates can be batch loaded and then read sequentially on the FLIPR system without variation in signal between plates.

PediaSure Enteral Formula has an osmolality of 335 mOsm/kg H20 and PediaSure Enteral Formula with Fiber and scFOS® has an osmolality of 345 mOsm/kg H20.

The originating company of Wolverine Tile Company began simply with the installation of porcelain panels for gas stations and fast food restaurants. Through strategic growth and expansion maneuvers, Wolverine Building Group now consists of four separate divisions handling more than $100 Million in volume each year in almost every market of construction from healthcare, education, and retail to industrial, churches, and multi-unit residential. | Back to Top

Reduction in the number of components in media design is essential for cell growth. Eagle’s basal media (BME) and Eagle’s minimum essential medium have found wide-ranging uses and are both available commercially.

Formulations include a complex mixture of salts, carbohydrates, amino acids, vitamins, hormones, and growth factors. The salt concentration needs to be isotonic to prevent osmotic imbalances.

Scientists know that pandemics have occured on a regular basis through history, and they are concerned that the avian influenza virus that is now found in Asia and some European countries (known as H5N1) could slightly change, or mutate, in a way that would allow it to pass easily from person-to-person.

MPEG (.mpeg, .mpg files) is a media type that is not proprietary in type and was created by a consortium, and is a streaming format. AVI (.avi) is a media format originally created by Microsoft, but is not proprietary, and is very common on the web; AVI is generally not a streaming format, although there are some kind that do stream. Microsoft has its own kinds of media, with the .asf and .wmv video formats and the .wmp audio format. Macromedia (with Flash/Shockwave) has its own format (.

you may recall, a number of the classier 5.25" diskette brands employed (still employ?) a lubricant on their jacket liners. While the lube worked to reduce drag and noise, it also, evidently, served as a growth medium for a particularly nasty plastic and/or oxide-eating fungus! It's probably a good idea to check each of your old diskettes. Immediately backup any diskettes with splotchy discolorations.

All hairs have differing cycles of growth activity and are not visible on the surface of the skin at the same time. hiar normally grows for its usual cycle and then naturally sheds and replaces itself. Following active growing periods, hair follicles go into a dormant phase. The period of dormancy may last for an indefinite perido of time, however, replacement hairs usually appear with 3 to 12 months.

Hair growth is caused by several factors: hormonal changes at different stages of the life cycle such as teenage years, pregnancy and menopause. Other causes are genetic such as heredity, or reactions to medication as well as hormonal and glandular imbalances such as Polycystic Ovarian Syndrome (PCOS).

Only adults should take it. People with diabetes, cancer, or heart problems must consult with their physician. Any woman who is pregnant or lactating should not take the product.

When HGH was originally discovered researchers learned that children needed ample amounts in order to grow properly. Thus the name growth hormone.

No. Growth hormone is not an anabolic steroid but has similar effects. Anabolic steroids are synthetic products that do not exist in nature. Growth hormone is a naturally occurring substance made by the pituitary gland.

All cow milk contains growth hormones, which are identical to human growth hormones. These are being sold as a health food and are considered beneficial in the health food industry. Skim milk could cause acne for several reasons, notably because it depletes vitamin A and also because, if it is pasteurized, the body mounts an immune response to it. Raw whole milk often clears up acne.
