Background

Interleukin 7(IL-7)is a mature protein of 177 amino acids with a signal sequence of 25 amino acids and a calculated mass of 17.4kDa. Recombinant human IL-7 stimulated the proliferation of murine pre-B cells and was active on cells harvested from human bone marrow that are enriched for B-lineage progenitor cells.

IL-7 is a proteinaceous biological response modifier that has a bioactive tertiary structure dependent on disulfide bond formation.

IL-7-stimulated pro-B cells partially differentiated into a pre-B cell population, on the basis of the loss of CD34 and terminal deoxynucleotidyl (TdT) expression, and the acquisition of cytoplasmic mu heavy chains.

Surprisingly Effective and Convenient!
Color: Bag Petrol
I wasn’t sure what to expect with the purse clean ball, but it has turned out to be a great little gadget! It’s simple to use—just toss it into your purse, and it quietly works to pick up crumbs, lint, and small debris. The sticky interior does an excellent job of collecting all the random dirt that accumulates, and it’s easy to clean—just rinse it under water, let it dry, and it’s good as new. I also love that it’s compact and doesn’t take up much space in my bag. If you want an easy way to keep your purse tidy without constantly emptying and shaking it out, this is a fun and effective solution. Highly recommend it for anyone who likes to keep their bags neat and clean!

Highly recommend
Color: Black
I love these so much. They make the perfect stocking stuffer but as a chronically messy person, I love throwing them in my purse or backpack. They pick up so much and are really easy to wash off.

Clean Your Purse
Color: Pink
This ball is pretty cool. It acts like a lint roller inside your purse getting all the dirt, crumbs, & lint that accumulates at the bottom. When it's looking nasty, you can rinse it off in the sink & it's good to go back in your purse. It's one of my best Amazon purchases and I will probably buy again if/when the sticky wears off or having a spare on hand.

Value for money
Color: Blue
This definitely is something to have. Used it a lot while travelling and for office use as well. It takes out all the gunk from the bag and is easy to clean as well

Used for a year.

Had this in a back pack for a year and wow. The dirt collected is kinda shocking. I will buy more of these for different bags!
