Does specific activity of a recombinant protein vary between lots?
Specific activity will vary for each lot and for the type of experiment that is done to validate it, but all passed lots will have activity within the established ED50 range for the product and we guarantee that our products will have lot-to-lot consistency. Please conduct an experiment-specific validation to find the optimal ED50 for your system.
Have your recombinants been tested for stability?
Our testing shows that the recombinant proteins are able to withstand room temperature for a week without losing activity. In addition the recombinant proteins were also found to withstand four cycles of freeze and thaw without losing activity.
How do you convert activity as an ED50 in ng/ml to a specific activity in Units/mg?
Use formula Specific activity (Units/mg) = 10e6/ ED50 (ng/mL)
How does the activity of your recombinant proteins compare to competitors?
We quality control each and every lot of recombinant protein. Not only do we check its bioactivity, but we also compare it against other commercially available recombinant proteins. We make sure each recombinant protein’s activity is at least as good as or better than the competition’s. In order to provide you with the best possible product, we ensure that our testing process is rigorous and thorough. If you’re curious and eager to make the switch to BioLegend recombinants, contact your sales representative today!
What is the specific activity or ED50 of my recombinant protein?
The specific activity range of the protein is indicated on the product datasheets. Because the exact activity values on a per unit basis can largely fluctuate depending on a number of factors, including the nature of the assay, cell density, age of cells/passage number, culture media used, and end user technique, the specific activity is best defined as a range and we guarantee the specific activity of all our lots will be within the range indicated on the datasheet. Please note this only applies to recombinants labeled for use in bioassays. ELISA standard recombinant proteins are not recommended for bioassay usage as they are not tested for these applications.

Donald Trump sent a top ally to sleep with the 'low energy' and 'boring' tone of his speech to the UN General Assembly.
The President of the United States addressed the UN during its congress in New York just after 3pm GMT.
While the speech hit a number of key talking points, it was the tone of Mr Trump's delivery that caught the most attention.
And one critic took to social media to say the 73-year-old sounded 'medicated'.
At points the US leader seemed to slur his words in a lengthy speech that rarely got out of first gear.
As well as seemingly sending most of social media into a sleepy daze, Mr Trump's address appeared to be too much for the US's Secretary of Commerce Wilbur Ross.
The American investor was filmed in the crowd with his eyes closed.
As Mr Ross snoozed, people took to Twitter to register their waning interest with his delivery.
"He is a terrible speaker," one Twitter user wrote.
Mr Trump's speech failed to get out of first gear
"So boring. So monotone. I’m also having a very hard time believing anything he says." 
Another Twitter user suggested the President's speech stuck too closely to the script.
"Trump sounds medicated as he drones on through his boring teleprompter UN speech," they said.
"There has never been a more boring delivery of a speech on the world stage as you gave today at the UN," a third said.
"Why do you even bother? It does nothing except embarrass yourself and our country."
While the high energy, raucous delivery associated with Mr Trump's appearances at campaign rallies clearly wasn't visible, the President did touch on many of his favourite talking points.
The energy associated with Mr Trump's campaign rallies was not there
At the head of the address he took the time to advance his America First world view.
"Wise leaders put the good of their own people and their own country first," he said.
"The future does not belong to globalists. The future belongs to patriots.
"The future belongs to sovereign and independent nations, who protect their citizens, respect their neighbors and honor the differences that make each country special and unique."
Mr Trump also promoted his domestic record, calling the US "the world's most powerful nation" at the beginning of the speech.
He went on to highlight the $2.5 trillion his administration had spent on the US military since he took office, before accusing the Iranian government of 'squandering' its wealth in its pursuit of nuclear weapons.
"America will never tolerate such anti-semitic hate," the President said of the Middle Eastern country.
"Fanatics have long used hatred of Israel to distract form their failures."
Mr Trump accused Iran of anti-semitism
The Republican leader did say that his country was "ready to embrace friendship with all who genuinely embrace peace and respect", ramping down previously fiery rhetoric aimed at Iran.
The government of China was also in the firing line of the President.
"Not only has China declined to adopt promised reforms, it has embraced an economic model, dependent on massive market barriers, heavy state subsidies, currency manipulation, product dumping, forced technology transfers and the theft of intellectual property and also trade secrets on a grand scale," he said.
Boris Johnson received a much needed boost from Mr Trump
In a much needed boost for Boris Johnson, who is in New York at the UN Assembly, Mr Trump said he was working closely with UK prime minister on a trade deal.
He said: "I have made clear that we stand ready to enter an exceptional new trade agreement with the UK which will bring tremendous trade benefits to both of our countries.
"I have been working closely with Boris Johnson for a terrific new trade deal."

A primer and tutorial on Elliptical Curve Cryptography. More of an intuitive approach than mathematical. Good to get started and develop intuitions. Good visualizations as well.
