Application
Biotin-conjugated bovine serum albumin binds selectively to different vascular subsets in lymphoid tissues, as demonstrated by both fluorescent and enzymohistochemical techniques, and thus offers a histochemical probe for identification of select microvascular endothelia in lymphoid tissues.
Biotin-conjugated bovine serum albumin binds selectively to different vascular subsets in lymphoid tissues, as demonstrated by both fluorescent and enzymohistochemical techniques, and thus offers a histochemical probe for identification of select microvascular endothelia in lymphoid tissues. In spleen, biotin-BSA binds to red pulp sinuses, but not white pulp vessels (including the central arteriole) nor the marginal sinus. In the thymus, prominent binding was restricted to the capillaries of the corticomedullary area.
Biotin labeled bovine albumin has been used as a component in myosin V processivity experiments. It has also been used to provide biotin tags for neutravidin coating and also to suppress nonspecific cell adhesion during preparation of tension gauge tether (TGT) surface.
Physical form
Contains sodium citrate buffer salts

What is the molecular weight for biotin labeled bovine(Product A8549, Albumin)?
1 réponse-
In order to determine the molecular weight of this product, review the lot specific Certificate of Analysis for the Degree of Substitution (this provides the moles of biotin per mol of albumin). For lot SLCM9516, the Degree of Substitution is 8 mols biotin per mol of albumin. 8 x 244.31 (MW of biotin) + 66,430 (MW of BSA) = 68,384
